It is the desire, it is the anger born of the quality of Rajas, all devouring, all sinful; know this as the foe in this world. Even a wise man acts in accordance to his own Nature; beings follow to Nature; what can restraint do? No doubt we are slaves of our Nature but that does not mean that we are doomed to our destiny. Thoughts are your friends and thoughts are your enemies. Imbibe your friends and do not let your enemies nest in your heart. Thus you can change the course of events-destiny. Therefore control your senses and stay with this sinful desire destroyer of wisdom and discrimination. The Yogi who strives assiduity, purified of all the sins perfecting him through many births, attains to the highest goal.
