Bhagavad Gita 6.15
युञ्जन्नेवं सदाऽऽत्मानं योगी नियतमानसः।शान्तिं निर्वाणपरमां मत्संस्थामधिगच्छति॥
yuñjannevaṃ sadā''tmānaṃ yogī niyatamānasaḥ |śāntiṃ nirvāṇaparamāṃ matsaṃsthāmadhigacchati ||
Thus, always keeping the mind balanced, the yogi, with the mind controlled, attains the peace abiding in Me, culminating in liberation.
Thus, keeping his mind always in communion with Me and subduing his thoughts, he shall attain that Peace which is Mine and will lead him to liberation at last.
Our plain-language meaning of this verse is waiting for scholar review.
