Every centre is adapted to work with a certain kind of energy, and it receives exactly what it needs; but all the centres steal from one another, and so a centre that needs a higher kind of energy is reduced to working with a lower kind, or a centre suited for working with a less potent energy uses a more potent, more explosive energy. This is how the machine works at present. Imagine several furnaces—one has to work on crude oil, another on wood, a third on petrol. Suppose the one designed for wood is given petrol: we can expect nothing but explosions. And then imagine a furnace designed for petrol and you will see that it cannot work properly on wood or coal. We must distinguish four energies working through us: physical or mechanical energy—for instance, moving this table; life energy which makes the body absorb food, reconstruct tissues, and so on; psychic or mental energy, with which the centres work, and most important of all, energy of consciousness. Energy of consciousness is not recognized by psychology and by scientific schools. Consciousness is regarded as part of psychic functions. Other schools deny consciousness altogether and regard everything as mechanical. Some schools deny the existence of life energy. But life energy is different from mechanical energy, and living matter can be created only from living matter. All growth proceeds with life energy. Psychic energy is the energy with which centres work. They can work with consciousness or without consciousness, but the results are different, although not so different that the difference can be easily distinguished in others. One can know consciousness only in oneself. For every thought, feeling or action, or for being conscious, we must have corresponding energy. If we have not got it, we go down and work with lower energy—lead merely an animal or vegetable life. Then again we accumulate energy, again have thoughts, can again be conscious for a short time. Even an enormous amount of physical energy cannot produce a thought. For thought a different, a stronger solution is necessary. And consciousness requires a still quicker, more explosive energy.
