Beware of impure, evil things. Watch what you eat and drink; that it does not have impure things in it. Because when you eat them, your spirituality weakens and your body is harmed bringing illness. Eat pure food and be with pure people. Don't be in dirty places with dirty friends. There are many beautiful things, but they are dirty at their core. Look at the core of things. If it is pure admire it, and like it.
