आत्मैव ह्यात्मनो बन्धुरात्मैव रिपुरात्मनः।।6.5।।
6.5 One should save oneself by oneself; one should not lower oneself. For oneself is verily ones onw friend; oneself is verily ones own enemy.
6.5 By the self (Atman), i.e., by the mind, which is unattached to sense-objects, one should raise the self. One should not allow the self to sink by a mind which is of the contrary kind. For the self alone, i.e., the mind alone is the friend of the self; and it alone is the foe of the self. [The figure of speech here is of Samsara as the ocean in which the individual self is like an object with liability to sink. What causes its sinking is the lingering attachments of the mind to some objects, though in the discipline of Jnana Yoga one may keep aloof from such objects. A mind with such attachments is the foe and without them, the friend.]
