Antahkarana

In Vedāntic literature, this antaḥkaraṇa (internal organ) is organised into four parts:

1. Ahaṃkāra (ego) – identifies the Atman (self) with the body as 'I'
2. Buddhi (intellect) – controls decision making
3. Manas (mind) – controls sankalpa (will or resolution)
4. Citta (memory) – deals with remembering and forgetting
