Excerpt taken from P.D.Ouspensky's book 'In Search Of The Miraculous' (pp 235-235):
"Accumulators work in the following way," he said. "Let us suppose that a man is working or is reading a difficult book and trying to understand it, in which case several 'rolls' revolve in the thinking apparatus in his head. Or let us suppose that he is walking up a hill and is getting tired, in which case the 'rolls' revolve in the moving center.
"In the first instance the intellectual center, and in the second the moving center, draw the energy necessary for their work from the small accumulators. When an accumulator is nearly empty a man feels tired. He would like to stop, to sit down if he is walking, to think of something else if he is solving a difficult problem. But quite unexpectedly he feels an inflow of strength, and he is once more able to walk or to work. This means that the center has become connected with the second accumulator and is taking energy from it. Meanwhile the first accumulator is refilling with energy from the large accumulator. The work of the center goes on. The man continues to walk or to work. Sometimes a short rest is required to insure this connection. Sometimes a shock, sometimes an effort. Anyway, the work goes on. After a certain time the store of energy in the second accumulator also becomes exhausted. The man again feels tired.
"Again an external shock, or a short rest, or a cigarette, or an effort, and he is connected with the first accumulator. But it may easily happen that the center has drawn energy from the second accumulator so quickly that the first one has had no time to refill itself from the large accumulator, and has taken only half the energy it can hold; it is only half full.
"Having become reconnected with the first accumulator the center begins to draw energy from it, while the second accumulator becomes connected with and draws energy from the large accumulator. But this time the first accumulator was only half full. The center quickly exhausts its energy, and in the meantime the second accumulator has succeeded in getting only a quarter full. The center becomes connected with it, swiftly exhausts all its energy, and connects once more with the first accumulator, and so on. After a certain time the organism is brought to such a state that neither of the small accumulators has a drop of energy left. This time the man feels really tired. He almost falls down, he almost drops asleep, or else his organism becomes affected, he starts a headache, palpitations begin, or he feels sick.
"Then suddenly, again a short rest, or an external shock, or an effort, brings a new flow of energy and the man is once more able to think, to walk, or to work. "This means that the center has become connected directly to the large accumulator. The large accumulator contains an enormous amount of energy. Connected with the large accumulator a man is literally able to perform miracles. But of course, if the 'rolls' continue to turn and energy which is made from air, food, and impressions continues to pour out of the large accumulator faster than it pours in, then there comes a moment when the large accumulator is drained of all energy and the organism dies. But this happens very seldom. Usually the organism automatically stops working long before this. Special conditions are necessary to cause the organism to die exhausted of all its energy. In ordinary conditions a man will fall asleep or he will faint or he will develop some internal complication which will stop the work a long time before the real danger.
"One need not, therefore, be afraid of efforts; the danger of dying from them is not at all great. It is much easier to die from inaction, from laziness, and from the fear of making efforts.
"Our aim, on the contrary, is to learn to connect the necessary center with the large accumulator. So long as we are unable to do this, all our work will be wasted because we shall fall asleep before our efforts can give any kind of results.
"Small accumulators suffice for the ordinary, everyday work of life. But for work on oneself, for inner growth, and for the efforts which are required of a man who enters the way, the energy from these small accumulators is not enough.
"We must learn how to draw energy straight from the large accumulator.
"This however is possible only with the help of the emotional center. It is essential that this be understood. The connection with the large accumulator can be effected only through the emotional center. The instinctive, moving, and intellectual centers, by themselves, can feed only on the small accumulators.
"This is precisely what people do not understand. Therefore their aim must be the development of the activity of the emotional center. The emotional center is an apparatus much more subtle than the intellectual center, particularly if we take into consideration the fact that in the whole of the intellectual center the only part that works is the formatory apparatus and that many things are quite inaccessible to the intellectual center.
"If anyone desires to know and to understand more than he actually knows and understands, he must remember that this new knowledge and this new understanding will come through the emotional center and not through the intellectual center."
In addition to what he had said about accumulators G. made some very interesting remarks about yawning and about laughter.
"There are two incomprehensible functions of our organism inexplicable from the scientific point of view," he said, "although naturally science does not admit them to be inexplicable; these are yawning and laughter. Neither the one nor the other can be rightly understood explained without knowing about accumulators and their role in the organism.
"You have noticed that you yawn when you are tired. This is especially noticeable, for instance, in the mountains, when a man who is unaccustomed to them yawns almost continually while he is ascending a mountain. Yawning is the pumping of energy into the small accumulators".
