Shad Darshanas (षड्दर्शनानि)

The Six Darsanas (Shad Darshanas, Sanskrit षड्दर्शनानि) are the intellectual section of the Hindu writings. They are schools of philosophy based on the Vedas.

कणादेन तु संप्रोक्तं शास्त्रं वैशेषिकं महत् । गौतमेन तथा न्यायं सांख्यं तु कपिलेन वै ॥

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

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

These are the six systems of Hindu philosophy which are known as Shad Darsanas. They are:

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 (Badrayana or Vyasa) 

The six heterodox systems of philosophy are:

1. The Materialistic School of Charvaka
2. The System of the Jainas
3. The School of Presentationists or Vaibhashikas (Buddhistic)
4. The School of Representationists or Sautrantikas (Buddhistic)
5. The School of Idealism or Yogacharas (Buddhistic)
6. The School of Nihilism or the Madhyamikas (Buddhistic).

When the term Shad Darsanas is employed, it means the six Astika Darsanas. In this article these six orthodox (Astika) systems will be discussed.

Detailed Discussion

Indian Philosophy has six Aastika schools called the Shad-darsana--the six ways of seeing things, the six different schools of thought. The six schools of philosophy are six demonstrations of Truth. Each school has developed, systematised and correlated the various parts of the Veda in its own way. Each system has its Sutrakara, i.e. the one great Rishi, who systematised the doctrines of the school and put them in short aphorisms or Sutras.

The Sutras are terse and laconic. The Rishis have condensed their thoughts in the aphorisms. It is very difficult to understand them without the help of commentaries by great sages or Rishis. Hence, there arose many commentators or Bhashyakaras. These Bhashyas are glosses, notes and commentaries on the original commentaries.
