asaṃśayaṃ mahābāho mano durnigrahaṃ calaṃ |abhyāsena tu kaunteya vairāgyeṇa ca gṛhyate ||
Without doubt, O mighty-armed one, the mind is restless and hard to restrain. But it can be held, O son of Kunti, through steady practice and through detachment.
Explanation
Arjuna has just said the mind is as hard to control as the wind. Krishna agrees that this is true, then offers the remedy: steady practice (abhyāsa), meaning repeated effort to hold the mind on one focus, and detachment (vairāgya), meaning loosening the pull of desires and sense objects. The two work together to bring the mind under control.
