By spiritual development, we can see what is really needed, what we need. How much food do we need? How much sleep do we need? Each person is different. For individual person, it should be considered: how much sex do they actually need to be peaceful? These are all given by the yoga process. What is the minimum, what is the basic norm that is sufficient for us to be materially peaceful if we are spiritually satisfied. Materially, we are always going to have demands as long as we have the body : the body has to eat , the body has to sleep etc., but how much? Therefore the yogi is regulated. He Regulates his material activity. Materially, he becomes content, because spiritually he is satisfied. The principle is spiritual satisfaction .
