You are continually building, and so externalizing in your body conditions most akin to the thoughts and emotions you entertain. And not only are you so building from within, but you are also continually drawing from without, forces of a kindred nature. Your particular kind of thought connects you with a similar order of thought from without. If it is bright, hopeful, cheerful, you connect yourself with a current of thought of this nature. If it is sad, fearing, despondent, then this is the order of thought you connect yourself with. If the latter is the order of your thought, then perhaps unconsciously and by degrees you have been connecting yourself with it. You need to go back and pick up again a part of your child nature, with its careless and cheerful type of thought. "The minds of the group of children at play are unconsciously concentrated in drawing to their bodies a current of playful thought. Place a child by itself, deprive it of its companions, and soon it will mope and become slow of movement. It is cut off from that peculiar thought current and is literally 'out of its element.' "You need to bring again this current of playful thought to you which has gradually been turned off. You are too serious or sad, or absorbed in the serious affairs of life. You can be playful and cheerful without being puerile or silly. You can carry on business all the better for being in the playful mood when your mind is off your business. There is nothing but ill resulting from the permanent mood of sadness and seriousness,--the mood which by many so long maintained makes it actually difficult for them to smile at all. "At eighteen or twenty you commenced growing out of the more playful tendency of early youth. You took hold of the more serious side of life. You went into some business. You became more or less involved in its cares, perplexities and responsibilities. Or, as man or woman, you entered on some phase of life involving care or trouble. Or you became absorbed in some game of business which, as you followed it, left no time for play. Then as you associated with older people you absorbed their old ideas, their mechanical methods of thinking, their acceptance of errors without question or thought of question. In all this you opened your mind to a heavy, care-laden current of thought. Into this you glided unconsciously. That thought is materialized in your blood and flesh. The seen of your body is a deposit or crystallization of the unseen element ever flowing to your body from your mind. Years pass on and you find that your movements are stiff and cumbrous,--that you can with difficulty climb a tree, as at fourteen. Your mind has all this time been sending to your body these heavy, inelastic elements, making your body what now it is. . . .
