Drawing back from Desire

As to sexual impulse. Regard it not as something sinful and horrible and attractive at the same time, but as a mistake and wrong movement of the lower nature. Reject it entirely, not by struggling with it, but by drawing back from it, detaching yourself and refusing your consent; look at it as something not your own, but imposed on you by a force of Nature outside you. Refuse all consent to the imposition. If anything in your vital consents, insist on that part of you withdrawing its consent. Call in the Divine Force to help you in your withdrawal and refusal. If you can do this quietly and resolutely and patiently, in the end your inner will will prevail against the habit of the outer Nature. …

The trouble of the sex-impulse is bound to dwindle away if you are in earnest about getting rid of it. The difficulty is that part of your nature (especially, the lower vital and the subconscient which is active in sleep) keeps the memory and attachment to these movements, and you do not open these parts and make them accept the Mother’s Light and Force to purify them. If you did that and, instead of lamenting and getting troubled and clinging to the idea that you cannot get rid of these things, insisted quietly with a calm faith and patient resolution on their disappearance, separating yourself from them, refusing to accept them or at all regard them as part of yourself, they would after a time lose their force and dwindle.
