Shad Darshanas (षड्दर्शनानि)

The Six Darsanas or Shad Darshanas (Samskrit : षड्दर्शनानि) are the intellectual and philosophical discussions of Bharatiya shastras. 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 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.

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's 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 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.

Growth of Bharatiya Darshana Shastras

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.

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. 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 Hindu philosophy or 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) 

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 (Buddhistic)
   • The School of Representationists or Sautrantikas (Buddhistic)
   • The School of Idealism or Yogacharas (Buddhistic)
   • The School of Nihilism or the Madhyamikas (Buddhistic).

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.

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. 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 and Punarjana siddhanta
2. Mukti siddhanta
3. Atma (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.

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. 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. 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.

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.
