- Bāhyātmā - It is the physical body comprising the various limbs and subject to birth and death. It is also called as the outer ātman.
- Antarātmā - It is the inner ātman. It is the mind composed of the sukṣma-bhūtas or the subtle elements. It is also responsible for the functions of the senses and various states like thinking, feeling and willing.
- Paramātmā - It is the third and the last and is also called as the ‘puruṣa,’ the Supreme Self or the Person. He is the true Self who is subtler than the subtlest. He is also described as the one beyond all the changes and destruction, the eternally pure witness of all, the infinite, the indestructible.
