Sex is sacred, a sacred source of power. The reason mystics everywhere place such emphasis on control of sexual desire is that the journey of sadhana is so arduous, so demanding, that we need to draw on every trace of its power to reach the goal. If you want to rise to your full height, if you want to love to your full depth, then try gradually to master sex. Try to harness it, not strangle or suffocate it, so that this immense power is released to flow towards all in love. Every time you put someone else first, you draw on a little of this power and transform it. Tenderness, patience, selfless service, hard work for others without thought of personal reward — all these harness the raw energy of sexual desire and help to transform it, little by little into an abiding flow of joy. . . .
If you feel strong sexual drives, congratulations. If you feel haunted by sex day and night, you are a person rich in resources. It's like striking oil in your backyard; you have a little Arabia to supply you with all the power you need.
