परित्राणाय साधूनां विनाशाय च दुष्कृताम् ।धर्मसंस्थापनार्थाय संभवामि युगे युगे ॥
paritrāṇāya sādhūnāṃ vināśāya ca duṣkṛtām |dharmasaṃsthāpanārthāya saṃbhavāmi yuge yuge ||
To protect the good, to destroy those who do wrong, and to firmly re-establish dharma, I come into being age after age.
Explanation
Krishna continues his answer to Arjuna, explaining why he takes birth whenever dharma (moral and cosmic order) declines. He names three purposes: protecting the virtuous (sādhu), removing wrongdoers, and re-establishing dharma. Traditions differ on how to read his "coming into being" (sambhavāmi): many devotional schools take it as a real descent (avatāra) of God, while others read it as a manifestation through maya or as the divine appearing within human awareness.
