Animal urges need to be repressed because we do not live in the forest, by ourselves, without consequence.
We have society and values for the protection of the weak. If we gave in to every urge and allowed animal sense to take over, why not just carry clubs around and knock out and screw anything that walks? I think the reason is obvious, I'm sure many women would
not appreciate this.
Desires can control us better than we understand. Food, sex, drugs all can be addictive. Eat to much, you can become bedridden and die from a heart attack. Have sex to much, even protected can lead to disease. To many drugs, well just ask a few of the best
musicians to come into our lives. Oh wait you can't because they're dead.
You can find examples where this seemingly natural desires, sex food, comfort and escape all can become abused and lead to not only physical but I believe mental debilitation.
As for you mentioning catholics, I myself am catholic. And I find what has happened in the catholic church sad and appaling. But I do believe in the pracitce of complete abstinence for the sake of religious practice. It is for this reason in fact that the catholic
church has many child abusers. A person with urges for children know that it is wrong, they know that it hurts the child and leaves the children with lifelong complexes. So they go into the priesthood hoping that they can face their desires. It does not always
work, but many times it does.
Sexual abstinence is not unique to the catholic church. In ancient India, monks believed that the body produced tapas, which is like heat which the body creates and sexual abstinence allows this tapas to grow which leads to greaty mental faculty.
I believe that controling the body, meditation, controled breathing exercices, working out, sexual abstinence are all forms of controling the mind and our spirit.
My point is, mind your desires, they can get the best of you. Control your body, and you can have a clear mind.
