1. If you have not yet received the Precepts then you have not violated them. However, that being said, you still violate the “Precepts against nature,” meaning that it’s not a good thing. In the strict sense, masturbation is not a violation of the Deviant Sex Precept, but it is a violation of your inherent wisdom.

After you learn the proper methodology, you will eventually be able to eliminate your errant thoughts and realize Non-thought.
