Indian schools of philosophy are known as darsanas (seeing) and divided into two categories
 namely Astika (believer in the Vedas) and Nastika (non-believer in the Vedas). Astika are Nyaya, Vaisheshik, Sakhya, Yoga, Mimamsa and Vedanta. Nastika are Carvaka, Jainism and Buddhism. Others are a mixture of the ideas of these systems.

Indian Schools of Philosophy

Indian schools of philosophy are divided into 6 Astika(believer in Vedas) Darsana-s popularly known as “Shad darsana” all of which accept the testimony of the Vedas

The Shad-Darsanas (the six schools of philosophy) or the Shat-Sastras are:

• The NYAYA, founded by Gautama Rishi,  variously estimated to have been composed between 6th-century BCE and 2nd-century CE.

• The VAISESHIKA by Kanada Rishi,  around the 6th to 2nd century BC.

• The SANKHYA by Kapila Muni,  While He pre-dates Buddha, it is unclear which century he lived in, with some suggesting 6th-century BCE. Others place him in the 7th century BCE. This places him in the late Vedic period (1500 BCE to 500 BCE), and he has been called a Vedic sage.

• The YOGA by Patanjali Maharshi,  2nd century BCE to 4th century CE,

• The PURVA MIMAMSA by Jaimini, (ca. 300–200 BCE

• The UTTARA MIMAMSA or VEDANTA by Badarayana or vyasa. (?500-200 B.C)
