Chapter 6, Verse 27
Part of 6: Dhyān Yog — ध्यानयोगप्रशान्तमनसं ह्येनं योगिनं सुखमुत्तमम्। उपैति शान्तरजसं ब्रह्मभूतमकल्मषम्॥
praśhānta-manasaṁ hyenaṁ yoginaṁ sukham uttamam upaiti śhānta-rajasaṁ brahma-bhūtam akalmaṣham
Supreme Bliss indeed comes to this Yogi whose mind is made peaceful, whose passion is quelled, who has become Brahman, and who is free from sin.
In this verse and in the next also the Lord describes the benefits of Yoga. Supreme (eternal, unalloyed and uninterrupted) bliss comes to the Yogi whose mind is perfectly serene, who has calmed his passionate nature, who has destroyed all sorts of attachments, who has attained knowledge of the Self and thus become a Jivanmukta or one who is liberated while living, who feels that all is Brahman only, and who is taintless, i.e., who is not affected by Dharma or Adharma (good or evil).
