"Through detachment man learns to withdraw his interest and his consciousness from the things of the senses, and to turn a deaf ear to the calls of the lower nature. Detachment imposes a new rhythm upon the man. Through learning the lesson of dispassion he becomes immune to the suffering of the lower nature as he detaches his interest from secondary things and the non-essentials, and centers it upon the higher realities. Through the practice of discrimination the mind learns to select the good, the beautiful and the true. These three practices, leading to a changed attitude towards life and reality, will, when held sanely, bring in the rule of wisdom."
