To be understood (SB cantos 4 - 12)
Srimad-Bhagavatam
SB Canto 4
SB 4.3.23, Purport:
The living entity is constitutionally pure. Asaṅgo hy ayaṁ puruṣaḥ. In the Vedic literature it is said that the soul is always pure and uncontaminated by material attachment. The identification of the body with the soul is due to misunderstanding. As soon as one is fully Kṛṣṇa conscious it is to be understood that one is in his pure, original constitutional position. This state of existence is called śuddha-sattva, which means that it is transcendental to the material qualities. Since this śuddha-sattva existence is under the direct action of the internal potency, in this state the activities of material consciousness stop.
