Bhagavad Gita 6.35

श्री भगवानुवाच · śrī bhagavānuvāca

असंशयं महाबाहो मनो दुर्निग्रहं चलं।अभ्यासेन तु कौन्तेय वैराग्येण च गृह्यते॥

asaṃśayaṃ mahābāho mano durnigrahaṃ calaṃ |abhyāsena tu kaunteya vairāgyeṇa ca gṛhyate ||

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."

Lord Shri Krishna replied: Doubtless, O Mighty One, the mind is fickle and exceedingly difficult to restrain; however, O Son of Kunti, with practice and renunciation, it can be done.

Our plain-language meaning of this verse is waiting for scholar review.
