He himself, oh descendant of Bharata, as well as his mind and five senses, comes to rest when he has reached the first course of meditation by the incessant practice of yoga. That bliss of him whose self is thus controlled, will not be attained by means of any kind of human effort or fate. Endowed with that bliss he will delight in the activity of meditation. In this way the yogins attain to that nirvana which is free from disease. (MBh. 12. 188.20-22)
