अर्जुन उवाच,
किं तद्ब्रह्म किमध्यात्मं किं कर्म पुरुषोत्तम। अधिभूतं च किं प्रोक्तमधिदैवं किमुच्यते ॥१॥
What is that Brahman? What is the self (adhyātma)? What is action (karma), O Supreme Person, What is described as pertaining to the underlying principle of being (adhibhūta)? And what is referred to as the underlying principle of destiny or divinity (adhidaiva)?"
अधियज्ञः कथं कोऽत्र देहेऽस्मिन् मधुसूदन। प्रयाणकाले च कथं ज्ञेयोऽसि नियतात्मभिः ॥२॥
O Madhusūdana, how is the principle of sacrifice (adhiyajña) present in this body, and where? And how are (You) to be known at the time of departure by those of a controlled mind?
श्रीभगवानुवाच, अक्षरं ब्रह्म परमं स्वभावोऽध्यात्ममुच्यते। भूतभावोद्भवकरो विसर्गः कर्मसञ्ज्ञितः ॥३॥
The Blessed Lord said: "The imperishable (akṣara) is the Supreme Brahman. One's essential nature (svabhāva) is called 'adhyātma', pertaining to the self. We know action (karma) as the special arising of the universe that causes beings to exist.
