“The Lord is like the sun, which illuminates everything and cannot be illuminated by anyone.”
This is from the Srimad-Bhagavatam 8.3.10
[This chapter of the Srimad-Bhagavatam is entitled “Gajendra’s Prayers of Surrender.” In this chapter, the King of the elephants, Gajendra, having been attacked by a crocodile, prayed to the Personality of Godhead for protection.]
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.
The Supreme Personality of Godhead, Krishna, 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 atma-pradipa.
The Lord is like the sun, which illuminates everything and cannot be illuminated by anyone. Therefore, if one is serious about understanding the Supreme, one must receive enlightenment from Him, as instructed in Bhagavad-gita. One cannot understand the Supreme Personality of Godhead by one’s mental, physical or intellectual powers.
