Most of us can learn to live in perfect comfort on higher levels of power. Everyone knows that on any given day there are energies slumbering in him which the incitements of that day do not call forth. Compared with what we ought to be, we are only half awake. It is evident that our organism has stored-up reserves of energy that are ordinarily not called upon, deeper and deeper strata of explosible material, ready for use by anyone who probes so deep. The human individual usually lives far within his limits.
- William James
