During such emergencies as battle, worry, or exhausting work, this excess energy is essentially used up, and the organism is asexual. However, ordinarily, energy would keep piling up, so that either the organism would have to grow continually or eventually burst unless some mechanism were present to discharge it after it reached a certain level. This level is known as the lumination point and, in the healthy individual, is felt as sexual excitement. Where excitation is blocked, the level of excitation is felt as tension or restlessness or other discomfort. One remembers, here, Freud's concept of sublimation.
Sublimation is effective to a very limited extent in preventing stasis.
Energy builds up to the point of sexual excitement, but the individual finds himself confronted with the necessity of holding back. He pulls back his pelvis, he tightens the muscles of his thighs and buttocks, he holds his breath and clenches his teeth and does not allow himself to look at anything that would disturb his resolve. Eventually he loses his sensation of sexual desire but finds his body tight from tensed muscles. He is armored. This process may continue until all the muscles of his body are involved, and still the energy increases.
