The same is true of the mind. The mind can develop a kind of boredom which is very depleting of your energy, and you have to know how to stimulate your mind by perhaps reading a book if you are home, something that really gives you impetus; and it will give you magnetism. And remember that the magnetism of each plane can be communicated to the next plane, and so the magnetism of the mind will communicate itself, for example, to the physical body. The same thing is true, of course, that it can communicate itself higher.
