Krishna responds to Arjuna's despair with absolute, calm authority, delivering the foundational algorithm of cognitive mastery. He says: Without a doubt (asaṃśayaṃ), O mighty-armed one (mahā-bāho), the mind is incredibly difficult to curb and restrain (mano durnigrahaṃ), and it is naturally restless and flickering (calam). However (tu), O son of Kunti, it can absolutely be captured, controlled, and brought to heel (gṛhyate) through two specific mechanisms: by relentless, dedicated practice (abhyāsena) and by the cultivation of profound detachment (vairāgyeṇa ca).
