"Just as the purpose of eating is to satisfy hunger, not greed, so the sex instinct is designed for the propagation of the species according to natural law, never for the kindling of insatiable longings. Destroy wrong desires now; otherwise they will follow you after the astral body is torn from its physical casing. Even when the flesh is weak, the mind should be constantly resistant. If temptation assails you with cruel force, overcome it by impersonal analysis and indomitable will. Every natural passion can be mastered. Conserve your powers. Be like the capacious ocean, absorbing within all the tributary rivers of the senses. Small yearnings are openings in the reservoir of your inner peace, permitting healing waters to be wasted in the desert soil of materialism. The forceful activating impulse of wrong desire is the greatest enemy to the happiness of man. Roam in the world as a lion of self-control; see that the frogs of weakness don't kick you around."
