Arjuna's challenge (4.4): how could Kṛṣṇa have taught in the remote past? This opens the Avatāra teaching (4.5–4.14): Kṛṣṇa takes birth age after age through ātma-māyayā for the protection of the good, destruction of the wicked, and re-establishment of Dharma. Then: deepening of Karma Yoga through BG 4.18 (seeing inaction in action), culminating in Jñāna as the supreme purifier (4.36–4.38) and the sword of knowledge (4.42).","key_verses_detail":{"BG_4_6":{"iast":"ajo 'pi sann avyayātmā bhūtānām īśvaro 'pi san / prakṛtiṃ svām adhiṣṭhāya sambhavāmy ātma-māyayā","translation":"Though I am birthless and my Self is imperishable, though I am the Lord of all beings — yet I come into being through my own power (Māyā), governing my own Prakṛti.","note":"The paradox of divine birth. ātma-māyayā: Advaita — appearance through Māyā (not a real birth of absolute Brahman); Viśiṣṭādvaita — Viṣṇu's sovereign divine power, with a real body of śuddha-sattva (pure Sattva)."},"BG_4_7_8":{"iast_7":"yadā yadā hi dharmasya glānir bhavati bhārata / abhyutthānam adharmasya tadātmānaṃ sṛjāmy aham","iast_8":"paritrāṇāya sādhūnāṃ vināśāya ca duṣkṛtām / dharma-saṃsthāpanārthāya sambhavāmi yuge yuge","translation":"Whenever there is a decline of Dharma and an uprising of Adharma, then I project Myself.

As fire reduces fuel to ashes, the fire of knowledge reduces all karma to ashes. There is nothing as purifying as knowledge.","note":"Jñāna-agni (fire of knowledge): does not merely reduce karma but eliminates the Avidyā that is karma's binding root. Total, irreversible transformation."},"BG_4_42":{"iast":"tasmād ajñāna-sambhūtaṃ hṛt-sthaṃ jñānāsinātmanaḥ / chittvainaṃ saṃśayaṃ yogam ātiṣṭhottiṣṭha bhārata","translation":"Therefore, having cut asunder with the sword of knowledge this doubt in your heart born of ignorance — take refuge in Yoga.
