“Floating in the tank after a busy day’s work brings a great relief. Suddenly all of the stimulation of holding one upright against gravity disappears. One realizes that a good deal of the fatigue accumulated during the day is caused by keeping one’s body upright in a gravitational field. From a neurophysiological standpoint, one has immediately freed up very large masses of neurons from the necessity of constant computations (as to the direction of gravity, the programming by visual and acoustic inputs, by temperature changes, etcetera). For example, one’s cerebellum is now freed for uses other than balancing the body. In summary, then,”

Sometimes I wake up in the middle of the night with an idea that I want to work out, so rather than disturb my wife, I float in the tank and work out the idea at great length and in fine detail. I am then able to put it down on paper or to dictate it in the morning. For a businessperson, a scientist, a professional of any sort, this is a boon: to be able to think, free of physical fatigue of the body. The method allows one to become free within a few minutes.”
