Mantak Chia wisdom words

Que. If the goal is to build up one's sexual energy, what's the harm of sleeping with a lot of different women (or men) to increase your Life energy? 

Ans : The goal is not to build up one's sexual energy—it is to transform raw sexual energy into a refined subtle energy. Sex is only one means of doing that. Promiscuity can easily lower your energy if you choose partners with moral or physical weakness. If you lie with degenerates, it may hurt you, in that you can temporarily acquire your partner's vileness. By exchanging subtle energy, you actually absorb the other's substance. You become the other person and assume new karmic burdens. This is why old couples resemble each other so closely: they have exchanged so much energy that they are made of the same life-stuff. This practice accelerates this union, but elevates it to a higher level of spiritual experience.  So the best advice I can give is to never compromise your integrity of body, mind and spirit. In choosing a lover you are choosing your destiny, so make sure you love the woman with whom you have sex. Then you will be in harmony with what flows from the exchange and your actions will be proper. If you think you can love two women at once, be ready to spend double the life energy to transform and balance their energy. I doubt if many men can really do that and feel deep serenity. For the sake of simplicity, limit yourself to one woman at a time. It takes a lot of time and energy to cultivate the subtle energies to a deep level. It is impossible to define love precisely. You have to consult your inner voice. But cultivating your life energy sensitizes you to your conscience. What was a distant whisper before may become a very loud voice. For your own sake, do not abandon your integrity for the sake of physical pleasure or the pretense that you are doing deep spiritual exercises. If you sleep with one whom you don't love, your subtle energies will not be in balance and psychic warfare can begin. This will take its toll no matter how far apart you are physically until you sever or heal the psychic connection. It's better to be honest in the beginning. For the same reason make love only when you feel true tenderness within yourself. Your power to love will thus grow stronger. Selfish or manipulative use of sex even with someone with whom you are in love can cause great disharmony. If you feel unable to use your sexual power lovingly, then do not use it at all! Sex is a gleaming, sharp, two-edged sword, a healing tool that can quickly become a weapon. If used for base purposes, it cuts you mercilessly. If you haven't found a partner with whom you can be truly gentle, then simply touch no one. Go back to building your internal energy and when it gets high you will either attract a quality lover or learn a deeper level within yourself.
