Bhagavad Gita Chapter 8, Verse 1

अर्जुन उवाच | किं तद् ब्रह्म किमध्यात्मं किं कर्म पुरुषोत्तम | अधिभूतं च किं प्रोक्तमधिदैवं किमुच्यते ||

arjuna uvāca kiṁ tad brahma kim adhyātmaṁ kiṁ karma puruṣottama adhibhūtaṁ ca kiṁ proktam adhidaivaṁ kim ucyate

Arjuna said: What is that Brahman? What is Adhyatma? What is karma? What is Adhibhuta? And what is Adhidaiva?

After Krishna's revelations about His divine nature in Chapter 7, Arjuna now asks fundamental questions about the nature of reality. 'Kim tad brahma'—what is that Brahman, the eternal Absolute? 'Kim adhyatma'—what is Adhyatma, the Self that dwells in the body? 'Kim karma'—what is karma, the action that binds or liberates? 'Kim adhibhutam'—what are the material elements? 'Kim adhidaivam'—what are the divine controllers? These questions reveal Arjuna's deep desire to understand the structure of existence—from the absolute to the relative, from the eternal to the temporal. He's not just asking for definitions; he's seeking the framework that will help him understand death, rebirth, and liberation.
