The ancients said: Obedience is cheap, and vice is expensive. It means that it is easy to go down with the current, and difficult to go up against the current. Intentional lust follows the flow of lustful thoughts, straying from the original and chasing delusions, which is cheap. Abstinence from prostitution is to go against the flow of lustful thoughts, to get rid of the delusion and return to the original, it is precious. May everyone be noble and not mean.
