How to get rid of lust in a spiritual way?

I tell you that all the passions repose within the molecules of the body—anger, lust, love, hate, sadness, and so on, are manifested therein. In cheerfulness the molecules of the features are grandly illuminated—in sadness, the reverse. The licentious, lustful man cannot conceal his true nature. When anger is exhibited, see how quickly the infinitesimal particles composing the face are darkened.
