 “He who attendeth to the inclinations of the senses, in them hath a concern; from this concern is created passion, from passion anger, from anger is produced delusion, from delusion a loss of the memory, from the loss of memory loss of discrimination, and from loss of discrimination loss of all!

But he who, free from attachment or repulsion for objects, experienceth them through the senses and organs, with his heart obedient to his will, attains to tranquility of thought. And this tranquil state attained, therefrom shall soon result a separation from all troubles; and his mind being thus at ease, fixed upon one object, it embraceth wisdom from all sides.

The man whose heart and mind are not at rest is without wisdom or the power of contemplation; who doth not practice reflection, hath no calm; and how can a man without calm obtain happiness? The uncontrolled heart, following the dictates of the moving passions, snatcheth away his spiritual knowledge, as the storm the bark upon the raging ocean.

Therefore, O great armed one, he is possessed of spiritual knowledge whose senses are withheld from objects of sense. What is night to those who are unenlightened is as day to his gaze; what seems as day is known to him as night, the night of ignorance. Such is the self-governed Sage!
