The middle course consists in restraining the desire-nature by temperance. There are three ways of thus subduing it: (a) withholding gratification; ... (b) imposing religious observances; (c) invoking the Divine help for mastery over it. If you follow this threefold method, the desire-nature will be amenable to discipline.—Letter 83.
Discipline of the Desire-Nature. (Continued.)
The discipline of the desire-nature is recommended by all creeds and nations, and is known by Sages as a means of developing the supersensuous faculties....

Avoid as much as possible the thought of personality and its activities, and never follow the promptings of the desire-nature. It is thy existence that veils Thee. Had there been the veil of a single activity, it could be uplifted by another opposite activity.

It should not be forgotten in this connection that the discipline of the desire-nature means the transmutation of its qualities, not the destruction of its essential nature—for that is impossible. But its existence need not be regarded as dangerous after it has been subdued by the inner Ruler.

It is food that imparts strength and weakness, purity and foulness to all the organs of the body. It must be pure in quality and moderate in quantity.—Letter 84.
Alienation from the Desire-Nature.
Alienation from the personality is the first step to acquaintance with God. The one is a necessary condition for the other. All aspirants find fault with, and impose tasks on, the desire-nature, so that this wall of separation be pulled down, and a way be found to the Divine Sanctuary.
So long as thou lookest down upon a single soul as inferior to thee, thou art self-conceited, and blind to the Divine Presence. "If thou hast knowledge, put that knowledge into practice; solve thy difficulties by knowledge and practice (combined)." ...
