|Arjuna inquired: "O my Lord, O Supreme Person, what is Brahman? What is the self? What are fruitive activities? What is this material manifestation? And what are the demigods? Please explain this to me.|
How does this Lord of sacrifice live in the body, and in which part does He live, O Madhusudana? And how can those engaged in devotional service know you at the time of death?"
The Supreme Lord said, "The indestructible, transcendental living entity is called Brahman, and his eternal nature is called the self. Action pertaining to the development of these material bodies is called karma, or fruitive activities.
Physical nature is known to be endlessly mutable. The universe is the cosmic form of the Supreme Lord, and I am that Lord represented as the Supersoul, dwelling in the heart of every embodied being.
And whoever, at the time of death quits his body, remembering Me alone, at once attains My nature, doubtlessly.
Whatever state of being one remembers when he quits his body, that state he will attain without fail.
Therefore, Arjuna you should always think of Me in the form of Krishna and at the same time carry out your prescribed duty of fighting. With your activities dedicated to Me and your mind and intelligence fixed on Me, you will attain Me without doubt. He who meditates on the Supreme Personality of Godhead, his mind constantly engaged in remembering Me, undeviated from the path, he, O Partha [Arjuna], is sure to reach Me.
One should meditate upon the Supreme Person as the one who knows everything, as he who is the oldest, who is the controller, who is smaller than the smallest, who is the maintainer of everything, who is beyond all material conception, who is inconceivable, and who is always a person. He is luminous like the sun and, being transcendental, is beyond this material nature.
