Īśvarakṛṣṇa

Systematizer of Sāṃkhya — the dualism of consciousness (puruṣa) and nature (prakṛti).

SāṃkhyaClassical IndiaIndian320–380 CE◦ India4th century CE

Overview

The author of the Sāṃkhyakārikā, the earliest surviving systematic text of Sāṃkhya — one of the oldest and most influential of the six orthodox schools. Sāṃkhya is a dualist, enumerationist philosophy: reality consists of many pure consciousnesses (puruṣa) and one primordial nature (prakṛti), which evolves into mind, senses, and world through the interplay of three qualities (guṇas). Liberation comes from discriminating consciousness from nature. Sāṃkhya's metaphysics underlies classical Yoga and pervades Indian thought.

What they supported — and why

Dualism of puruṣa and prakṛti

SupportedReality has two ultimate kinds — pure, passive consciousness (puruṣa, which is plural) and active, unconscious nature (prakṛti).

WhyThe witness that is aware cannot be the same as the changing objects it observes, so consciousness and nature must be distinct.

Evolution of nature through the three guṇas

SupportedPrakṛti evolves into intellect, ego, mind, senses, and elements through the balance and disturbance of three qualities — sattva, rajas, tamas.

WhyThe ordered variety of the world arises from a single nature unfolding under its three constituent tendencies.

Liberation through discriminative knowledge

SupportedBondage is the mistaken identification of consciousness with nature; liberation is discerning their difference.

WhySuffering comes from consciousness misidentifying itself with mind and body; realizing their separateness frees it.
