Krishna answers Arjuna's first three questions with absolute, dictionary-level precision. He defines: 1. That which is utterly indestructible and supreme (akṣaraṃ paramaṃ) is called Brahman (brahma). 2. The essential, eternal nature or localized manifestation of that Brahman (svabhāvo) is called Adhyātma or the self (adhyātmam ucyate). 3. The creative action and generative force (visargaḥ) which brings about the material existence, development, and creation of all living entities (bhūta-bhāvodbhava-karo) is technically defined as Karma (karma-sañjñitaḥ).
