Chapter II, Section 1d

For his mind is steady whose senses are under his control. The man who ponders over objects of sense forms an attachment to them; from (that) attachment is produced desire; and from desire anger is produced ; from anger results want of discrimination ; from want of discrimination, confusion of the memory; from confusion of the memory, loss of reason; and in consequence of loss of reason. he is utterly ruined. But the self-restrained man who moves among objects with senses under the control of his own self, and free from affection and aversion, obtains tranquillity . When there is tranquillity, all his miseries are destroyed, for the mind of him whose heart is tranquil soon becomes steady. He who is not self-restrained has no steadiness of mind; nor has he who is not self-restrained perseverance in the pursuit of self-knowledge; there is no tranquillity for him who does not persevere in the pursuit of self-knowledge; and whence can there be happiness for one who is not tranquil? For the heart which follows the rambling senses leads away his judgment, as the wind leads a boat astray upon the waters. Therefore, O you of mighty arms! his mind is steady whose senses are restrained on all sides from objects of sense. The self-restrained man is awake, when it is night for all beings; and when all beings are awake, that is the night of the right-seeing sage . He into whom all objects of desire enter, as waters enter the ocean, which, (though) replenished, (still) keeps its position unmoved,-he only obtains tranquillity; not he who desires (those) objects of desire. The man who, casting off all desires, lives free from attachments, who is free from egoism , and from (the feeling that this or that is) mine , obtains tranquillity. This, O son of P ri thâ! is the Brahmic state; attaining to this, one is never deluded; and remaining in it in (one's) last moments, one attains (brahma-nirvâ n a) the Brahmic bliss .
