We may reject the objects but desire for them may remain. Even the desire is lost when the Supreme is seen. The control should be both on the body and the mind. Self-discipline is not a matter of intelligence. It is a matter of will and emotions.
Self discipline is easy when there is vision of the Highest.
When a man dwells in his mind on the objects of sense, attachment to them is produced. From attachment springs desire and from desire comes anger. Desires may prove to be as resistless as the most powerful external forces. They may lift us into glory or hurl us into disgrace. When the soul is overcome by passion, its memory is lost, its intelligence is obscured and the man is ruined.
