Sloka 6.40
पार्थ नैवेह नामुत्र विनाशस्तस्य विद्यते ।
नहि कल्याणकृत्कश्िचद्दुर्गतिं तात गच्छति ॥
పార్థ నైవేహ నాముత్ర వినాశస్తస్య విద్యతే ।
నహి కల్యాణకృత్కశ్ిచద్దుర్గతిం తాత గచ్ఛతి ॥
pārtha naiveha nāmutra vināśastasya vidyate |
nahi kalyāṇakṛtkaścaddurgatiṃ tāta gacchati ||
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.
