Having said that no one can know him, Shree Krishna now states that some people do know him. Is he contradicting himself? No, he means that by self-efforts no one can know God, but if God himself bestows his grace upon someone, that fortunate soul gets to know him. Hence, all those who come to know God do so by virtue of his divine grace. As he mentions in verse 10 of this chapter: “To those whose minds are always united with me in loving devotion, I give the divine knowledge by which they can attain me.” Here, Shree Krishna says that those who know him as the Supreme Lord of all lords are not deluded. Such blessed souls become free from all reactions to their past and present actions, and develop loving devotion toward him.

To make the distinction between the souls and himself, Shree Krishna declares that he is loka maheśhwaram (the great Lord of all the abodes of existence). The same declaration has been made in the Śhwetāśhvatar Upaniṣhad:

tamīśhwarāṇāṁ paramaṁ maheśhwaraṁ
taṁ devatānāṁ paramaṁ cha daivataṁ
patiṁ patīnāṁ paramaṁ parastād
vidāma devaṁ bhuvaneśhamīḍyam


“The Supreme Lord is the Controller of all controllers; he is the God of all gods. He is the Beloved of all beloveds; he is the Ruler of the world, and beyond the material energy.”
