Sāṅkhya: Categories of the Absolute Truth and the Unfolding of Creation
Tattva-vicāra
मनो बुद्धिरहङ्कारश्चित्तमित्यन्तरात्मकम् । चतुर्धा लक्ष्यते भेदो वृत्त्या लक्षणरूपया ॥ १४ ॥
mano buddhir ahaṅkāraś cittam ity antar-ātmakam caturdhā lakṣyate bhedo vṛttyā lakṣaṇa-rūpayā
The subtle inner faculty is experienced in four aspects—mind, intelligence, false ego, and contaminated consciousness. They are distinguished only by their functions, for each bears its own characteristic.
The four internal senses, or subtle senses, described herein are defined by different characteristics. When pure consciousness is polluted by material contamination and when identification with the body becomes prominent, one is said to be situated under false ego. Consciousness is the function of the soul, and therefore behind consciousness there is soul. Consciousness polluted by material contamination is called ahaṅkāra.
In Canto 3, Kapila explains that the inner instrument (antahkaraṇa) is one, but it is understood as four—mind, intelligence, false ego, and consciousness—based on their different functions.
Kapila teaches Devahūti Sāṅkhya to help her discern the workings of the subtle body, so she can progress toward detachment, clear discrimination, and devotional self-realization.
Observe your inner experience by separating: thoughts (mind), decisions (intelligence), “I/me” identity claims (false ego), and underlying impressions/memory (consciousness). This clarity supports steadier devotion and better self-control.
