(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. The self of one who has subjugated his self and is tranquil, is absolutely concentrated (on itself), in the midst of cold and heat, pleasure and pain, as well as honour and dishonour.
