Bhagavad Gita Chapter 6, Verse 15
युञ्जन्नेवं सदात्मानं योगी नियतमानसः | शान्तिं निर्वाणपरमां मत्संस्थामधिगच्छति ||
yuñjann evaṁ sadātmānaṁ yogī niyata-mānasaḥ śāntiṁ nirvāṇa-paramāṁ mat-saṁsthām adhigacchati
Thus, always keeping the mind absorbed in the self, the yogi, with a disciplined mind, attains the supreme peace that abides in Me.
Krishna describes the result of proper meditation practice. 'Yuñjann evaṁ sadātmānaṁ'—thus (evam), practicing (yuñjan) constantly (sadā) with the self (ātmānam). This means: practicing meditation as described in the previous verses, always keeping the mind absorbed in the self. 'Yogī niyata-mānasaḥ'—the yogi (yogī) with disciplined (niyata) mind (mānasaḥ). This means: with controlled, focused mind, not scattered. 'Śāntiṁ nirvāṇa-paramāṁ mat-saṁsthām adhigacchati'—attains (adhigacchati) the supreme (paramām) peace (śāntim) that abides (saṁsthām) in Me (mat). This means: the yogi reaches the highest peace, the ultimate tranquility, which is established in Krishna, in the divine. This is the culmination of meditation practice—supreme peace, ultimate liberation, union with the divine. When you practice meditation correctly—with all the preparations, posture, mental state described—you attain this supreme peace.
