8.3.5 Mahabhrata 12.294.6-8. Meditation is the most powerful method of yoga
Vasistha said:
Now I shall tell you what you are asking about. Hear from me in secret how yoga should be performed, O great king.
Of the different ways in which yoga should be performed, meditation is the most powerful. And people who know the Vedas say that meditation is of two kinds:
Focus of the mind and breath-control.
Breath-control has attributes and focus of the mind is without attributes.
It is written in the Bhagavad Gita.
(18.52) Living apart, eating little, disciplined in speech, body and mind, always intent on the yoga of meditation (dhynayoga), taking refuge in dispassion, (18.53) giving up egoism, force, arrogance, lust, anger and grasping, unselfish, peaceful: [such a one] is fit for becoming Brahman.
