Shad Darshanas (षड्दर्शनानि)

The Six Darsanas or Shad Darshanas (Samskrit : षड्दर्शनानि) are the intellectual and philosophical discussions of Bharatiya shastras. Indian Philosophy has been intensely spiritual and has always emphasized on practical realization of truth as against the Western Philosophy which is essentially an intellectual quest for truth.

व्युत्पत्तिः || Etymology

The word 'philosophy' means 'love of learning'. It signifies a natural and necessary urge in human beings to know themselves and the world in which they 'live and move and have their being'. The word 'darshana' means 'vision' and also the 'instrument of vision'. It stands for the direct, intermediate and intuitive vision of Reality, the actual perception of Truth, and also includes the means which lead to this Realization.

Brhdaranyaka Upanishad describes the fundamental concept of Atma (आत्मा ) during Yajnavalkya Maitreyi Samvada as follows

साक्षात् मोक्षसाधनानि इमानि आत्मा वा अरे द्रष्टव्यः श्रोतव्यो मन्तव्यो निदिध्यासितव्यः । बृहदारण्यकोपनिषत् २-४-५ 

आत्मा वा अरे द्रष्टव्यः । See the Self is the keynote of all schools of Bharatiya Darshana Shastras. And this is also the reason why most of these schools are also religious sects.

Origin of Darshanas

The origin of Indian Philosophy, easily traced in the Vedas, has developed as an autonomous system practically unaffected by external influences.

The closing period of the Samhitas witness the conception of a single creator and controller of the Universe, variously called Prajapati, Visvakarman, Purusha, Hiranyagarbha, Brahmanaspati and Brahman. But this divine controller was yet only a deity and the quest to know the nature of this deity began in the Upanishads.

The Aranyakas mark the transition from the ritualistic (Karma-kanda) to the philosophic thought (Jnana-kanda). Here a mystic interpretation of the Vedic Yajnas is seen, which represent the prototype of philosophical thought processes. Aranyakas presented the ideas of symbolic forms of worship (pratika) and Prana (vital breath) was regarded as the most essential function for the life of man. This recognition of the superiority of Prana brought about a focus on the meditations on Prana as Brahman. However, though meditation took the place of yajnas, it was hardly adequate for the highest attainment of Brahman. Sages long accustomed to worship deities of visible manifestation could not easily dispense with the idea of seeking after a positive and definite content of Brahman. Nature of Brahman was unclear, for they had only a dim and dreamy vision of it in the deep craving of their souls which could not be translated into permanent terms. But this spark led them on the quest to understand the Brahman, and they found that by whatever means they tried to give a positive and definite content to the Ultimate Reality, Brahman, they failed. Yajnavalkya Maharshi conceptualized the Neti Neti philosophy and said "He the Atman is not this, nor this. He is inconceivable, unchangeable, untouched." Thus, it may be understood that we cannot describe Brahman by any positive content which is always limited by conceptual thought.

The fundamental idea which runs through the early Upanishads is that beneath the exterior world of change there is an unchangeable reality which is identical with that which underlies the essence on man (Brhd. Upan. 4.4.5.22). The sum and substance of the Upanishad teaching is involved in the equation Atman = Brahman. It may be noted that Atman was used in the Rig Veda to denote both the ultimate essence of the Universe and also the vital breath in man. Upanishads however, use the word Brahman to denote the ultimate essence of the Universe and Atman is reserved to denote the innermost essence in man and Upanishads emphatically declare that the two are one and the same.

Upon this foundation of the Upanishads, principal systems of philosophy developed with systematic treatises being written in short pregnant half sentences called Sutras, which did not elaborate the subject, but were intended for those who had direct elaborate oral instructions on the subject.

Systematization of Darshanas

It can be seen that the spirit of philosophical enquiry, although had begun in the days of the earliest Upanishads, had continued even in circles other than those of the Upanishads. The Buddha and Jaina activities were also probably happening concurrently as no reference to them is seen in the Upanishads. Thus, it can be said that there were different forms of philosophical inquiry in spheres other than those of the Upanishads, of which we have but scanty records. In the assemblies of the sages and their pupils, the views of the heretical or heterodox thinkers were probably discussed and refuted. So it may have continued until some illustrious member of the assembly such as Gautama or Kanada collected the purport of these discussions on various topics and problems, filled up many of the missing links, classified and arranged these on the form of a system of philosophy and recorded it in Sutras (सूत्रम्). Thus, the object of these treatises, whether Astika or Nastika Darshanas, is three-fold

1. To consolidate the teaching of the particular school to which they belong.
2. To criticize others where they diverge from a particular school.
3. To defend and uphold the school to which they belonged by putting forth references, explanations and interpretations in the form of commentaries.

Such was the high esteem and respect in which these writers of the Sutras were held by later day writers that whenever they had any new speculations to offer, these were reconciled with the doctrines of one or other of the existing systems, and put down as faithful interpretations of the system in the form of Commentaries (भाष्यम्). Thus, the literature of each school of Philosophy consists of its own Sutra with commentaries and super-commentaries upon it, as also of certain independent treatises (prakarana) which expound the doctrine as a whole with a view to aid beginners, or discuss one or more aspects of it from the standpoint of the advanced student. The chief sign of systematization is seen in the analysis of the nature and function of knowledge or to the problems of what and how we know. A common feature of all the systems is that they involve, if they do not actually start with, an investigation of Pramanas (प्रमाणम्).

Pramana is defined as the proximate means to valid knowledge or prama (प्रमा). They are usually regarded as a help not only in acquiring new knowledge, but also in verifying what is already known, so that logic as conceived in Bharatavarsha, is a science both of proof and of discovery. A Pramana, like perception, may reveal the existence and nature of things not hitherto known. It may also be the means of verification, as when an object apprehended by the organ of sight is tested by means of touch or when a doubt arising in respect of something inferred is cleared by actual observation. There is much divergence of opinion among Indian thinkers concerning the number of pramanas accepted among the schools. The number of pramanas they accept range from one to six in general categorized under Shad Pramanas (षड्प्रमाणाः).

Such was the hold of these systems upon scholars that all the orthodox teachers belonged to one or the other of these schools since the foundation of the systems of philosophy. Their pupils were thus naturally brought up in accordance with the views of their teachers. All the independence of their thinking was limited and enchained by the faith of the school to which they were attached. Instead of seeing growth of free lance thinking and new theories, India brought forth schools of pupils who carried the traditional views of a particular school from generation to generation, who explained and defended them against the attacks of other rival schools, which they constantly attacked in order to establish the superiority of the system to which they adhere. For example, sutras of the Nyaya system of philosophy are attributed to Gautama, also called as Akshapada. The series of commentaries written by many adherents of this system, on these sutras, while conforming to the tradition yet showing novelty in thinking may be summarized as follows:

• Vatsyayana composed the earliest commentary on Gautama sutras, called as Vatsyayana Bhashya. This was sharply criticized by Buddhist Dinnaga.
• Udyotakara wrote a commentary on this commentary called Bhashyavattika, including the answers to Dinnaga's criticisms.
• Vachaspati Misra wrote a commentary on Bhashyavattika called Varttika-tatparyatika (Nyaya-tatparyatika), to refute all objections against the Nyaya system made by rival schools particularly by the Buddhists.
• Udayana set forth another commentary called Nyaya-tatparyatika-parishuddhi on Vachaspati Misra's commentary.
• Varddharmana wrote a commentary called Nyaya-nibandha-prakasha on Udayana's commentary.
• Padmanabha Misra wrote a commentary called Varddhamanendu on Varddhamana's commentary.
• Sankara Misra wrote another commentary on this called Nyaya-tatparyamandana.

The names Vatsyayana, Vachaspati and Udayana are indeed very great, but even they contented themselves by writing commentaries on commentaries, and did not try to formulate any original system. The contributions of the successive commentators served to make each system more complete and stronger to enable it to hold its own successfully against the opposition and attacks of the rival schools. Hence no study of the Indian philosophy is adequate without the study of commentaries which had kept it living through the ages of history.

Classification of Bharatiya Shastras

Traditionally Bharatiya shastras involving the systems of philosophy was divided into two classes:

• Astika (अास्तिकः)
• Nastika (नास्तिकः)

The term Astika comes from the Samskrit word Asti (अस्ति । there is) is defined as one that accepts the authority of the Vedas (sacred scriptures of ancient India). The Nastika (न अस्ति । it is not) views are those which neither regard the Vedas as infallible nor try to establish their own validity on their authority.

अास्तिकदर्शनानि ॥ Astika Darshanas

The term Astika (Samskrit : अास्तिकः) according to Vachaspatyam means अस्ति परलोक इति मतिर्यस्य । one who believes in the existence of paraloka (other worlds). Some schools of philosophy are based on the Vedas all of which proclaim the existence of other lokas (worlds), punarjanma (rebirth), existence of a supreme power etc. Six systems of the Indian philosophy called popularly as the Shad Darsanas are the Astika darshanas. They include:

1.  न्यायः || Nyaya (Rishi Gautama)
2.  वैशेषिकः || Vaiseshika (Rishi Kanada)
3.  साङ्ख्यः || Samkhya (Kapila Muni)
4.  योगः || Yoga (Maharishi Patanjali)
5.  पूर्वमीमांसा || Poorva Mimamsa (Jaimini)
6. उत्तरमीमांसा || Uttara Mimamsa or वेदान्त || Vedanta (Badarayana or Vyasa) 

These are often grouped by twos, taken in order, since the are allied to each other. They last pair, (Poorva and Uttara Mimamsa, however, are not so closely akin in their theoretical aspects, according to a few scholars. They are the two schools which are directly based on the Veda. The remaining four schools, in their present form, declare allegiance to the Veda, but it is doubtful whether they were Vedic from the beginning of their history. Astika Darshanas regard the realm of being as by no means exhausted by common experience and acknowledges a unique pramana for knowing what lies beyond. It may be further divided into two classes

- one which believes that individual insight is ultimately adequate for a knowledge of the transcendental realm

- one which seeks the aid of revelation for it.

Together these may be described as intuitionalistic.

We find that Padma purana introduces these shastras in the following slokas

कणादेन तु संप्रोक्तं शास्त्रं वैशेषिकं महत् । गौतमेन तथा न्यायं सांख्यं तु कपिलेन वै ॥ (Padm. Pura.6.236.4-5)

kaṇādena tu saṃproktaṃ śāstraṃ vaiśeṣikaṃ mahat । gautamena tathā nyāyaṃ sāṃkhyaṃ tu kapilena vai ॥

Meaning : The Vaisheshika shastra has been elucidated by Kanada, while the Nyaya shastra was given by Gautama Rishi, and Samkhya shastra was by Kapila Rishi.

नास्तिकदर्शनानि ॥ Nastika Darshanas

The three fundamental heterodox systems of philosophy are :

1. The Materialistic School of Charvaka
2. The System of the Jainas
3. The Buddhistic System which can be classified further as follows:
   • The School of Presentationists or Vaibhashikas
   • The School of Representationists or Sautrantikas
   • The School of Idealism or Yogacharas
   • The School of Nihilism or the Madhyamikas.

The Nastika group assumes that reality is confined to what is given in common experience and is described as positivistic or empirical in nature.

When the term Shad Darsanas is employed, it means the six Astika Darsanas. In this article the six Astika systems of Indian Philosophy will be introduced.

दर्शनानं सांम्यम् ॥ Fundamental Points of Agreement

The systems of philosophy in India were not stirred up merely by the speculative demands of the human mind which has a natural inclination for indulging in abstract thought, but by deep craving after the realization of the religious purpose of life. It is to be noted that the postulates, aims and conditions for such a realization were found to be identical in all the conflicting systems that have evolved. It is remarkable that with the exception of the Charvaka materialists all the other systems agree on some fundamental points of importance, namely.

1. Karma (कर्म) and Punarjana (पुनर्जन्मः) siddhanta
2. Mukti (मुक्तिः) siddhanta
3. Atma (आत्मा । Soul) siddhanta

Whatever may be their differences of opinion in other matters, so far as the general postulates for the realization of the transcendent state were concerned, all systems were practically in thorough agreement.

कर्मसिद्धान्तः ॥ Karma Siddhanta

All the Indian shastras agree that whatever action is done by an individual leaves behind it some sort of potency which has the power to ordain for him joy or sorrow in the future accordingly as it is good or bad. Karma siddhanta traces the causes which determine an action to the very individual that performs those acts. When the fruits of the actions are such that they cannot be enjoyed in the present life or in human life, the individual has to take another birth as a man or any other being in order to suffer them, thereby creating Samsara or the continued existence of the Self (Jiva) in a succession of lives. Thus Punarjanma siddhanta or the theory of Transmigration, is a necessary corollary to Karma siddhanta. Proper observance of all ritualistic details during performance of yajnas was probably the earliest form of the Karma doctrine.

Astika systems believed that the unseen (adrusta) potency of the action generally required some time before it could be fit for giving the doer the merited punishment or enjoyment. These would often accumulate and prepare the items of suffering and enjoyment for the doer in his next life. Only the fruits of those actions which are extremely wicked or particularly good could be reaped in this life. The Law of Karma accordingly is not a blind mechanical law, but is essentially ethical. Belief in Karma establishes the conviction that there is in reality no unfairness in life, no bitterness, as one who believes in Karma neither blames God nor their neighbours but only themselves for the pain or sorrow in their lives.

Man has had an infinite number of past lives of the most varied nature and the instincts of each kind of life exist dormant in the life of every individual and thus whenever he takes rebirth the special instincts of that life (called vasana) come forth. In accordance with these vasanas the person passes through the painful or pleasurable experiences as determined for him by his action. Such actions and experiences cannot be avoided but those actions which have not matured are uprooted once for all if the person attains true knowledge as advocated by philosophy. But even such an emancipated (mukta) person has to pass through the good or bad experiences ordained for him by the actions just ripened for giving their fruits. If in the meantime he attains true knowledge, all his past accumulated actions become destroyed, and as his acts are neither virtuous nor wicked, no fresh karma for ripening is accumulated and thus he becomes divested of all karma after enjoying the fruits of the ripened karmas alone. Thus, in the last stage of contemplation, all karma being annihilated, and all activities having ceased, the soul leaves the body and goes up to the top of the universe, where the liberated souls stay for ever.

मोक्षसिद्धान्तः ॥ Moksha Siddhanta

Karma leads us to the endless cycle of Samsara and if we could divest ourselves of all emotions, ideas or desires as lead us to action we should find within us the actionless self which neither suffers nor enjoys, neither works nor undergoes rebirth. Various schools agree in the recognition of liberation or release (moksha) from this cycle of rebirths as the highest of human ends or values. Chaturvarga - Artha, Kama, Dharma and Moksha are the highly revered Purusharthas, or the values. While Artha and Kama which mean wealth and pleasure are purely worldly values, the other two - Dharma and Moksha are described as spiritual. Of them, moksha has come to be acknowledged as the highest of human values by all schools of thought.

When the Indians, wearied by the endless bustle and turmoil of worldly events, sought for and believed that somewhere a peaceful goal could be found, they generally hit upon the Self of man.

The belief that the soul could be realized in some stage as being permanently divested of all action, feelings or ideas, led logically to the conclusion that the connection of the soul with these worldly elements was extraneous, artificial or even illusory. In its true nature the soul is untouched by the impurities of our ordinary life, and it is through ignorance and passion as inherited from the cycle of karma from beginning-less time that we connect it with these. The realization of this transcendent state is the goal and final achievement of this endless cycle of births and rebirths through karma.

आत्मसिद्धन्तः ॥ Atma Siddhanta

All the Indian shastras except Buddhism admit the existence of a permanent entity variously called Atman, Purusha, Jiva or Soul. As to the exact nature of this soul there are indeed divergences of view.

• Nyaya calls it absolutely quantityless and characterless, indeterminate unconscious entity.
• Samkhya describes it as being of the nature of pure consciousness.
• Vedanta says that it is that fundamental point of unity implied in pure consciousness (चित् । chit), pure bliss (आनन्दम् । ananda) and pure being (सत् । sat).

But all agree in holding that it is pure and unsullied in its nature and that all impurities of action or passion do not form a real part of it. When all impurities are removed and the pure nature of the self is thoroughly and permanently apprehended and all other extraneous connections with it are absolutely dissociated.

कार्यवादः ॥ Karyavada or Theory of Causation

Upanishads are rightly regarded as the fountain-head of all Indian philosophy. All darshanas which critically discuss about the Atman, Brahman and Sristhi or the Origin of the world have the seeds of thought from the Upanishads. Based on describing the cause for the existence of the world, different theories have been put forward. The basic question involved in any theory of causation is :

Does the effect pre-exist in its material cause?

Broadly there are two ways of explaining the origin of the physical world.

Asatkaryavadins or Theory of Origination :

Asatkaryavadins or Arambhavadins believe that the effect is a new creation, a real beginning. The effect (karya) does not pre-exist (asat) in its material cause. It is said to be a plurality of ultimate reals which are supposed to be simple and atomic as traced to Nyaya-Vaisheshika.

Satkaryavadins or Theory of Evolution :

Satkaryavadins or Prarambhavadins believe that the effect is not a new creation but only an explicit manifestation of material It may be derived from a single substance which is assumed to be complex and all pervasive as advocated by Sankhya-Yoga.

विवेकज्ञानम् ॥ Viveka Jnana

Though the belief that the world is full of sorrow has not been equally prominently emphasized in all systems, yet it may be considered as being shared by all of them. It finds its strongest utterance in Samkhya, Yoga and Buddhism. This interminable chain of pleasurable and painful experiences does not lead one to a peaceful end but embroiling and entangling us in the meshes of karma, rebirth, and sorrow. All human experiences are essentially sorrowful and ultimately sorrow begetting. Sorrow is the ultimate truth of this process of the world. That which to an ordinary person seems pleasurable appears to a wise person or to a yogi who has a clearer vision as painful. The greater the knowledge the higher is the sensitiveness to sorrow and dissatisfaction with world experiences. This sorrow of worldly experiences cannot be removed by bringing in remedies for each sorrow, nor be avoided by mere inaction or suicide. The only way to get rid of it is by the culmination of moral greatness and true knowledge (ज्ञानम् । Jnana) which uproot sorrow once and for all. It is our ignorance that the self is intimately connected with the experiences of life or its pleasures, that leads us to action and arouses passion in us for the enjoyment of pleasures and other emotions and activities.

• The Upanishads tell us that the Vedas - the storehouse of knowledge - have been breathed forth from Him (Brhd. Upan. 2.4.10); but they regard the Karma-kanda as secondary, being only a help to purify the mind by which purification one is made fit to receive the real teaching about Brahman.
• We find in Chandogya Upanishad (7.2) the Narada Sanatkumara Samvada that even though one is well-versed in the knowledge of the Vedas, Mantras and the Chaturdasha Vidyas, he or she could still be ignorant about the Self. Only one who knows the Self goes beyond sorrow.
• The Mundakopanishad (1.1.4 and 5) tells us: "Two kinds of knowledge must be known, the higher and the lower. The lower knowledge is that which the Rk, Sama, Atharva, ceremonial, grammar give .... but the higher knowledge is that by which the immortal Brahman is known.
• In the Bhagavadgita (2.45 and 46)also Srikrishna asks Arjuna to rise above the three gunas.

Through the highest moral elevation a man may attain absolute dispassion towards world-experiences and retire in body, mind and speech from all worldly concerns. When the mind is so purified the Self shines in its true light and its true nature is rightly conceived. When this once done the self can never again be associated with passion or ignorance. Self at this stage ultimately dissociates from Chitta, which is the root of all emotions, ideas and actions. Thus, emancipated the self forever conquers all sorrow.

Unity in Indian Sadhana

Thus we see that all Indian shastras agreed upon the general principles of ethical conduct which must be followed for the attainment of salvation. There are indeed divergences in certain details or technical names, but the means to be adopted for purification are almost same as those advocated by the Yoga system. It is in later times that devotion (भक्तिः ।bhakti) is seen to occupy a more prominent place specially in Vaishnava schools of thought. Thus, although many differences are seen among the various shastras, yet their goal of life, their attitude towards the world and means for the attainment of the goal (साधना । sadhana) fundamentally being the same, advocates a unique unity in the practical sadhana of almost all the Indian philosophical schools of thought. The religious craving has been universal in India and this uniformity of sadhana has therefore secured for India a unity in all her aspirations and strivings.

Nyaya and Vaiseshika Darshanas

The Vaiseshika darshana is reagarded as conducive to the study of all systems. It deals with the Padarthas (पदार्थः । categories) and the entire universe is reduced to six or seven padarthas. The word 'padartha' means 'the meaning of a word' or 'the object signified by a word'. All objects of knowledge or all reals come under padartha. Padartha means an object which can be thought (ज्ञेयम् । jneya) and named (अभिधेयः । abhidheya). The Vaiseshika system is a pluralistic realism, a philosophy of identity and difference, which emphasizes that the heart of reality consists on difference. It is a mere catalogue of the knowables, an enumeration of the diverse reals without any attempt to synthesize them. Originally the Vaiseshika believed in the six categories and the seventh, that of Abhava or negation was added on later. The Vaiseshika divides all existent reals which are all objects of knowledge into two classes - bhava or being and abhava or non-being. All knowledge necessarily points to an object beyond and independent of it. Nyaya accepts the metaphysics of the Vaiseshika school and the accounts of matter, soul and God are almost the same as those in the Vaiseshika.

Nyaya-Vaiseshika believes in the doctrine of Asatkaryavada (असत्कार्यवादः ) which means that the effect does not pre-exist in its cause. The effect is a new beginning, a fresh creation. It is also called Arambhavada (आरम्भवादः) or Paramanukaranavada (परमाणुकरणवादः). Among the Nastika darshanas Hinayana Buddhism, Charvakas, and a group of Mimamsa believes in Asatkaryavada.

All physical things are produced by the combinations of atoms. Creation thus means the combination of atoms in different proportions and destruction means the dissolution of such combinations. The material cause of the Universe is neither produced nor destroyed. It is the eternal atoms. It is only the atomic combinations which are produced and which get destroyed. The following are the primary differences between Nyaya and Vaiseshika darshana concepts.

Vaiseshika	Nyaya
Recognizes seven padarthas and classifies all reals under them	Recognizes sixteen padarthas and includes all seven Vaiseshika padarthas in one of them called Prameya
Develops metaphysics and ontology (nature of beings and the relationships between them)	Develops logic and epistemology (the theory of knowledge)
Recognizes only two Pramanas : pratyaksha (perception) and anumana (inference)	Recognizes four Pramanas : perception, inference, Upamana (comparison) and shabda (verbal authority).

Samkhya and Yoga

The view of Samkhya and Yoga is called Prkriti-parinama-vada.

Yoga is intimately allied to Samkhya. The Bhagavadgita calls them one. Yoga means spiritual action and Samkhya means knowledge. Samkhya is theory and Yoga is practice. Yoga mostly accepts the postulates of Samkhya and shows the practical path by following which one may attain Vivekajnana which alone leads to liberation.

Yoga sutras are divided into four parts.

1. Samadhipada which deals with the nature and aim of concentration.
2. Sadhanapada explains the means to realise concentration.
3. Vibhutipada deals with the supra-normal powers which can be acquired through yoga.
4. Kaivalyapada describes the nature of liberation and the reality of the transcendental self.
