Sloka 6.19
यथा दीपो निवातस्थो नेङ्गते सोपमा स्मृता ।
योगिनो यतचित्तस्य युञ्जतो योगमात्मनः ॥
యథా దీపో నివాతస్థో నేఙ్గతే సోపమా స్మృతా ।
యోగినో యతచిత్తస్య యుఞ్జతో యోగమాత్మనః ॥
yathā dīpo nivātastho neṅgate sopamā smṛtā |
yogino yatacittasya yuñjato yogamātmanaḥ ||
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.
