When people do sadhana, there is a higher Nature that works within, the psychic and spiritual, and they have to put their nature under the influence of the psychic being and the higher spiritual self or of the Divine. Not only the vital and the body but the mind also has to learn the Divine Truth and obey the divine rule. But because of the lower nature and its continued hold on them, they are unable at first and for a long time to prevent their nature from following the old ways—even when they know or are told from within what to do or what not to do. It is only by persistent sadhana, by getting into the higher spiritual consciousness and spiritual nature that this difficulty can be overcome; but even for the strongest and best sadhaks it takes a long time.

If one is not master of one’s desires, one cannot be master of one’s thoughts.

It is always the habit of the vital being to find out things by which it persuades the mind and justifies its desires; and circumstances usually shape themselves to justify it still farther. For what we have within us creates the circumstances outside us.

To conquer a desire brings more joy than to satisfy it.

You must not mistake desire for will. Desire is an impulse: it seizes you, you know, it clings to you, holds you. And then, if you let desire do what it likes, well, it makes you do anything at all, and it makes use of your will. But usually, a desire is something violent, passionate and transient. Rarely is it very sustained; it does not have the stuff, the organisation of a sustained effort. When a desire seizes you, it can make you do anything whatever—but impulsively, not methodically.

Then lest a human cry should spoil the Truth
He tore desire up from its bleeding roots
And offered to the gods the vacant place.
