If we control our desire, if we almost order the body what he has to do or not, then we are temperate, one can also say moderate. Then we keep by such moderation those forces in the correct order which should help that we do not deliver the concerning organs to Lucifer in the next incarnation. Since we deliver the forces to Lucifer, which we spend to a passionate life. Most badly when the passions transport us into a state of drunkenness, when we feel well with dozing.
Where we lose our temperance, we always deliver forces to Lucifer. He takes these forces, but with them, he also takes the forces from us we need for the respiratory and the digestive organs. We return then with bad respiratory and digestive organs if we do not practice the virtue of moderation. Those who like to be captivated by their life of passions, who dedicate themselves to their passionate life, are the candidates for the decadent people of the future, for those people of the future who will suffer from all possible shortcomings of their physical bodies.
