Proper teaching is recognized with ease. You can know it without fail because it awakens within you that sensation which tells you this is something you have always known.
Frank HerbertThe mind can go either direction under stressโtoward positive or toward negative: on or off. Think of it as a spectrum whose extremes are unconsciousness at the negative end and hyperconsciousness at the positive end. The way the mind will lean under stress is strongly influenced by training.
Frank Herbert
