Biological needs are extremely difficult to deny or ignore. It is a battle. Won or lost it is a battle with casualties. Suppression of desire requires tremendous expenditures of energy. Henry David Thoreau.
Thought takes man out of servitude, into freedom.
Frank Oppenheimer, Ph.D., Nuclear Physicist, and lead scientist on developing the atomic bomb, when asked by his colleagues why he could produce reactions with atoms they, themselves, could not. Israeli researchers at the Weizmann Institute of Science provided the first physical proof of the quantum mechanical theory that, by the very act of watching, the observer affects the viewed reality. Thought triggers will, emotion, and desire. Will, emotion, and desire trigger bio-chemical reactions which in turn motivate behavior. To end the desire for behavior, one must end the thought that triggers the desire.
