Asceticism

Here is the English translation of the text you provided:

Since I was a monk, I believed I must be lost if I felt any carnal desire, such as lust, anger, hatred, envy, and the like, toward a brother. I tried many things, confessing every day, but it did not help; for such desires kept returning.

Religion requires a lifestyle of denying the desires of the body and following the dictates of the mind

Humankind consists of men and women. And each of them has two sides, mind and body. In believing in a religion, do you believe in it with your mind and body or with only your mind? It would be ideal for you to believe in it with your mind and body united. When they are not united, God centers first on the mind, which is the subject partner, in order to bring them into oneness.

Your conscience tells you to five for others according to the Principle. No matter how strong your body’s desire is, if you intentionally increase the force of your conscience beyond the force of your body, your body will follow it. If you cannot, you had better decrease your body’s force through fasting and asceticism. If clear water continually flows into a muddy pond, eventually the pond will become clear.

Please consider your own life. I don’t think you can deny that your mind and body often fight each other. How much longer are you going to allow this fight to continue? Ten years? A hundred years? Or will it not end even when you die? All beings in the universe were designed to display a definite order. This means God did not create us to exist in the imperfect state in which we now find ourselves. Your task now is to empower your mind and subdue your body. The grace of God will be with you in this effort.
