What Is the Antaḥkaraṇa?
Antaḥkaraṇa (from antaḥ = inner + karaṇa = instrument) refers to the fourfold internal instrument through which the jīvātman (individual soul) relates to the world:
- Manas (mind) — the deliberating faculty; the organ of doubt and consideration (saṃkalpā-vikalpa)
- Buddhi (intellect) — the faculty of determination and decision; the organ of judgment
- Ahaṅkāra (ego/I-maker) — the faculty that identifies the self with the body and its attributes; source of the false sense of separate independent selfhood
- Citta (memory/subconscious) — the store of impressions (vāsanās) from past experiences and actions
The Antaḥkaraṇa and Karma
The antaḥkaraṇa is an instrument through which embodied thought, desire, intention, recollection, and action operate, and it bears impressions (saṃskāras and vāsanās) associated with experience. Karma is not a quantity literally stored in this mental memory-organ: karmic bondage belongs to the jīva and bears fruit through Bhagavān's just governance, with the subtle body and internal organ serving as instruments during saṃsāra. The antaḥkaraṇa is nevertheless a central arena for discipline and purification.
Karma-yoga and jñāna-yoga purify the antaḥkaraṇa — particularly the ahaṅkāra — making it fit for bhakti-yoga and the contemplation of Brahman.
Antaḥkaraṇa and Prapatti
The moment of prapatti (surrender) involves the antaḥkaraṇa in all its dimensions: the manas resolves to surrender, the buddhi recognizes the Lord as the only upāya, the ahaṅkāra releases its claim to self-ownership, and the citta stores the impression of surrender as the deepest saṃskāra.
