SB Canto 8

The Supreme Personality of Godhead, Kṛṣṇa, cannot be understood by the individual soul through mental, physical or intellectual exercises. It is by the grace of the Supreme Personality of Godhead that the individual soul is enlightened. Therefore, the Lord is described here as ātma-pradīpa. The Lord is like the sun, which illuminates everything and cannot be illuminated by anyone.

SB 8.3.10, Translation and Purport

I offer my respectful obeisances unto the Supreme Personality of Godhead, the self-effulgent Supersoul, who is the witness in everyone's heart, who enlightens the individual soul and who cannot be reached by exercises of the mind, words or consciousness.
