Sanskrit
तस्मादज्ञानसम्भूतं हृत्स्थं ज्ञानासिनाऽऽत्मनः । छित्त्वैनं संशयं योगमातिष्ठोत्तिष्ठ भारत ॥
tasmād ajñāna-sambhūtaṃ hṛt-sthaṃ jñānāsinātmanaḥ chittvainaṃ saṃśayaṃ yogam ātiṣṭhottiṣṭha bhārata
Translation
Therefore, with the sword of the wisdom of the Self cleaving asunder this ignorance-born doubt dwelling in thy heart, be established in yoga. Stand up, O Bhârata.

Explanation
The chapter’s closing command completes a frame that opened all the way back in Chapter 1: cut this ignorance-born doubt sitting in the heart with the sword of self-knowledge, be established in yoga, and stand up — uttiṣṭha, the same summons to rise that Krishna issued more bluntly at 2.3, now earned through four chapters of argument rather than merely asserted. What began as Arjuna’s collapse into doubt and grief on the battlefield is answered here with a specific instrument, jñāna imaged as a weapon, rather than with a bare command to stop feeling that way.
