Bhagavad Gita 6.27

प्रशान्तमनसं ह्येनं योगिनं सुखमुत्तमम्।उपैति शान्तरजसं ब्रह्मभूतमकल्मषम्॥

praśāntamanasaṃ hyenaṃ yoginaṃ sukhamuttamam |upaiti śāntarajasaṃ brahmabhūtamakalmaṣam ||

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.

Supreme bliss is the lot of the sage whose mind attains peace, whose passions subside, who is without sin, and who becomes one with the Absolute.

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