Śaṅkarācārya's commentary

I dwell in the hearts (buddhi) of all sentient beings as their Self. Wherefore from Me, the Self of all sentient beings, are memory, knowledge, as well as their loss. Just as knowledge and memory occur in righteous persons as a result of their good deeds (puṇya-karman), so, as a result of their sins, loss of memory and knowledge occurs in the sinful. I, the Supreme Self, am to be known in all the Vedas. It is I who cause the Teaching of the Vedānta (Upaniṣads) to be handed down in regular succession, and It is I who know the Vedic Teaching.
