Sloka 6.20
यत्रोपरमते चित्तं निरुद्धं योगसेवया ।
यत्र चैवात्मनाऽऽत्मानं पश्यन्नात्मनि तुष्यति ॥
యత్రోపరమతే చిత్తం నిరుద్ధం యోగసేవయా ।
యత్ర చైవాత్మనాఽఽత్మానం పశ్యన్నాత్మని తుష్యతి ॥
yatroparamate cittaṃ niruddhaṃ yogasevayā |
yatra caivātmanā’’tmānaṃ paśyannātmani tuṣyati ||
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.
