The sixth chapter of the Bhagavad Gita is Dhyana Yoga. In this chapter, Krishna reveals the Yoga of Meditation and how to practise this Yoga. He discusses the role of action in preparing for Meditation, how performing duties in devotion purifies one's mind and heightens one's spiritual consciousness. He explains in detail the obstacles that one faces when trying to control their mind and the exact methods by which one can conquer their mind. He reveals how one can focus their mind on Paramatma and unite with the God.
The supreme Self of one who has control over the aggregate of his body and organs, and who is tranquil, becomes manifest. (He should be equipoised) [These words are supplied to complete the sentence.] in the midst of cold and heat, happiness and sorrow, as also honour and dishonour.OPEN VERSE
One whose mind is satisfied with knowledge and realization, who is unmoved, who has his organs under control, is said to be Self-absorbed. The yogi treats equally a lump of earth, a stone and gold.OPEN VERSE
He excels who has sameness of view with regard to a benefactor, a friend, a foe, a neutral, an arbiter, the hateful, a relative, good people and even sinners.OPEN VERSE
A yogi should constantly concentrate his mind by staying in a solitary place, alone, with mind and body controlled, free from expectations, (and) free from acquisition.OPEN VERSE
Having firmly established in a clean place his seat, neither too high nor too low, and made of cloth, skin and kusa-grass, placed successively one below the other;OPEN VERSE
(and) sitting on that seat, he should concentrate his mind for the purification of the internal organ, making the mind one-pointed and keeping the actions of the mind and senses under control.OPEN VERSE
