When one does not attach oneself to objects of sense, nor to action, renouncing all fancies, then one is said to have risen to devotion. (A man) should elevate his self by his self; he should not debase his self, for even (a man's) own self is his friend, (a man's) own self is also his enemy. To him who has subjugated his self by his self, his self is a friend; but to him who has not restrained his self, his own self behaves inimically, like an enemy.
