Chapter 6, Verse 35
Part of 6: Dhyān Yog — ध्यानयोगश्री भगवानुवाच असंशयं महाबाहो मनो दुर्निग्रहं चलं। अभ्यासेन तु कौन्तेय वैराग्येण च गृह्यते॥
śhrī bhagavān uvācha asanśhayaṁ mahā-bāho mano durnigrahaṁ chalam abhyāsena tu kaunteya vairāgyeṇa cha gṛihyate
The Blessed Lord said, "Undoubtedly, O mighty-armed Arjuna, the mind is difficult to control and restless; but with practice and dispassion, it can be restrained."
The constant or repeated effort to keep the wandering mind steady by constant meditation on the Lakshya (centre, ideal, goal or object of meditation) is Abhyasa or practice. The same idea or thought of the Self or God is constantly repeated. This constant repetition destroys Vikshepa or the vacillation of the mind and desires, and makes it steady and onepointed. Vairagya is dispassion or indifference to senseobjects in this world or in the other, here or hereafter, seen or unseen, heard or unheard, achieved through constantly looking into the evil in them (DoshaDrishti). You will have to train the mind by constant reflection on the immortal, allblissful Self. You must make the mind realise the transitory nature of the wordly enjoyments. You must suggest to the mind to look for its enjoyment not in the perishable and changing external objects but in the immortal, changeless Self within. Gradually the mind will be withdrawn from the external objects.
