Sloka 6.27
प्रशान्तमनसं ह्येनं योगिनं सुखमुत्तमम् ।
उपैति शान्तरजसं ब्रह्मभूतमकल्मषम् ॥
ప్రశాన్తమనసం హ్యేనం యోగినం సుఖముత్తమమ్ ।
ఉపైతి శాన్తరజసం బ్రహ్మభూతమకల్మషమ్ ॥
praśāntamanasaṃ hyenaṃ yoginaṃ sukhamuttamam |
upaiti śāntarajasaṃ brahmabhūtamakalmaṣam ||
About chapter 6
Krishna teaches the practice of meditation (dhyāna): one must lift oneself by one’s own mind, for the mind is both friend and enemy. He describes the seat, posture, moderation in food and sleep, and how to steady a restless mind through practice and detachment. No effort on this path is ever lost, and the yogi who worships with devotion is the highest.
