O best among the Bhāratas [Arjuna], four kinds of pious men render devotional service unto Methe distressed, the desirer of wealth, the inquisitive, and he who is searching for knowledge of the Absolute.
Men of small intelligence worship the demigods, and their fruits are limited and temporary. Those who worship the demigods go to the planets of the demigods, but My devotees ultimately reach My supreme planet.
O Arjuna, as the Supreme Personality of Godhead, I know everything that has happened in the past, all that is happening in the present, and all things that are yet to come. I also know all living entities; but Me no one knows.
Persons who have acted piously in previous lives and in this life, whose sinful actions are completely eradicated and who are freed from the duality of delusion, engage themselves in My service with determination.
Intelligent persons who are endeavoring for liberation from old age and death take refuge in Me in devotional service. They are actually Brahman because they entirely know everything about transcendental and fruitive activities.
Those who know Me as the Supreme Lord, as the governing principle of the material manifestation, who know Me as the one underlying all the demigods and as the one sustaining all sacrifices, can, with steadfast mind, understand and know Me even at the time of death.
