Energy created in the organism is kept in a certain big accumulator which is connected with two small accumulators placed near each centre. Supposing man begins to think and uses the energy of one of the small accumulators of the intellectual centre. The energy in the accumulator gets lower and lower, and when it is at its lowest he gets tired. Then he makes an effort, or has a short rest, or yawns, and becomes connected with the second small accumulator. It is very interesting that yawning is a special help provided by nature for passing from one accumulator to another. He goes on thinking and drawing energy from the second accumulator, is again tired, yawns, or lights a cigarette, and becomes connected again with the first small accumulator. But that accumulator may be only half filled and is quickly exhausted. He becomes connected once more with the second, which is only a quarter filled, and so it goes on until time may come when both accumulators are empty. If at that moment a man makes a special effort of the right kind he may become connected directly with the big accumulator. This is one explanation of miracles, for he will then have an enormous supply of energy. But this needs a very great effort—not an ordinary effort. If he exhausts the big accumulator he dies, but generally he falls asleep or becomes unconscious long before that, so there is no danger. In ordinary life this connection with the big accumulator sometimes happens in extraordinary circum stances, such as moments of extreme danger. This is why there is this system of small accumulators. If one could be easily connected with the big accumulator one might, for example, never stop being angry for a week, and then one would die. So generally one does not become connected with the big accumulator until one has control over negative emotions. Emotions are stronger than other functions, so if one were to get into a negative emotion and had unlimited energy it would be too dangerous
