🎯 How This Word Works in UPSC Writing

Rejecting established doctrine. In Indian philosophy the classification rests on a single criterion: acceptance of the authority of the Vedas. The six astika or orthodox schools, Samkhya, Yoga, Nyaya, Vaisheshika, Mimamsa and Vedanta, accept it, while the nastika or heterodox schools, Buddhism, Jainism, the Ajivikas and the Charvaka or Lokayata materialists, reject it. The persistent error is to read astika as theist and nastika as atheist. Classical Samkhya and Mimamsa are not concerned with a creator god yet remain orthodox, while Jainism maintains elaborate doctrines about liberated souls yet is heterodox, so the test is scriptural authority and not theology. The flowering of heterodox thought in the sixth century BCE is usually connected to material change, since agrarian surplus and expanding trade produced wealthy mercantile groups ranked below the priesthood in the varna order, to whom doctrines dispensing with costly sacrifice and hereditary priestly mediation naturally appealed.

⚖️ Don’t Confuse It With

Astika and nastika divide Indian schools by whether they accept the authority of the Vedas, not by belief in God, which is the most frequent confusion on this topic. Orthodox and heterodox are the conventional English renderings of that pair. Shramana names the wider wandering ascetic tradition from which Buddhism, Jainism and the Ajivikas emerged, standing against the brahmana tradition of Vedic ritual. Heresy presupposes a church with authority to define doctrine and expel dissenters, which is why the term fits the European context far better than the Indian one.
