बन्धुरात्माऽऽत्मनस्तस्य येनात्मैवात्मना जितः।
अनात्मनस्तु शत्रुत्वे वर्तेतात्मैव शत्रुवत्।।6.6।।
6.6 Of him, by whom has been conered his very self by the self, his self is the friend of his self. But, for one who has not conered his self, his self itself acts inimically like an enemy.
6.6 A person whose mind is conered by himself in relation to sense-objects, has that mind as his friend. In the case of one whose mind is not conered in this way, his own mind, like an enemy, remains hostile. The meaning is that it acts, against his attainment of supreme beatitude. It has been stated by Bhagavan Parasara also: The mind of man is the cause both of his bondage and his release. Its addiction to sense objects is the cause of his bondage; its separation from sense objects is the means of ones release (V. P., 6.7.28). The proper condition for the beginning of Yoga is now taught:
