Chapter 6 · Verse 18
Dhyana Yoga
ध्यानयोग
In plain words
Perfectly controlled mind The mind with onepointedness. When all desires for the objects of pleasure seen or unseen die the mind becomes very peaceful and rests steadily in the Supreme Self within. As the Yogi is perfectly harmonised as he has attained to oneness with the Self and as he has become identical with Brahman sense phenomena and bodily affections do not disturb him.
Translation
6.18 When the subdued mind rests on the self alone, then, free of all yearning for objects of desire, one is said to be fit for Yoga.
Meaning
Perfectly controlled mind The mind with onepointedness. When all desires for the objects of pleasure seen or unseen die the mind becomes very peaceful and rests steadily in the Supreme Self within. As the Yogi is perfectly harmonised as he has attained to oneness with the Self and as he has become identical with Brahman sense phenomena and bodily affections do not disturb him. He is conscious of his immortal imperishable and invincible nature. Yukta means united (with the Self) or harmonised or balanced. Without union with the Self neither harmony nor balance nor Samadhi is possible. (Cf. V.23VI.8)
