Indian philosophy is divided into Astika and Nastika schools. Astika schools accept Vedic authority, while Nastika schools reject it. This classification reflects the diversity of thought in ancient India and the central role of the Vedas in shaping philosophical discourse.
The Astika-Nastika divide goes beyond mere acceptance of scripture. It encompasses differing views on key concepts like atman, karma, and moksha. This classification helps us understand the rich tapestry of Indian philosophical thought and its evolution over time.
Astika vs Nastika Schools
Definition and Authority
- Astika schools accept Vedic authority while Nastika schools reject or do not rely on it
- Astika means "there is, there exists" in Sanskrit indicating belief in soul and afterlife
- Nastika means "there is not, there does not exist"
- Classification based on acceptance or rejection of Vedic authority rather than belief in God
- Astika schools considered orthodox within Hindu tradition
- Nastika schools viewed as heterodox or non-conformist
Key Concepts
- Astika schools generally accept atman (self), karma, and moksha
- Nastika schools may reject or reinterpret these concepts
- Atman refers to the eternal soul or self in Hindu philosophy
- Karma denotes the principle of cause and effect governing actions and their consequences
- Moksha signifies liberation from the cycle of rebirth and suffering
Examples and Distinctions
- Astika example Samkhya accepts atman but posits dualistic reality of Purusha (consciousness) and Prakriti (matter)
- Nastika example Buddhism denies eternal self (anatta) but accepts karma and nirvana (similar to moksha)
- Astika schools often incorporate theistic elements (Vedanta's concept of Brahman)
- Nastika schools like Charvaka embrace materialism and reject supernatural entities
