stimulated by a mental image, a connected picture of the painful state of the body wanting food and of the food which is able to change that state into one of pleasure; that is, he is now able to form mental images, and these stimulate him into activity. How great the change! No less than a change of the centre of consciousness from the animal to the human, one of the most significant changes in the evolving life. Now, for the first time, he does not wait to be pushed from without. He begins action from within, and the body obeys the impulse that comes from the centre, instead of the impact that strikes the centre from without. Now evolution becomes more rapid, for as this great change, one of the hardest of changes, is made, the intellect in man begins to cognise itself, and Self-consciousness begins to arise. Separation is recognised between its own centre, that thinks, and the things outside that make it think; the "I" and the "Not-I" arise, and the centre begins to shape itself and to be capable of growth. How shall the growth go on? By conflict. This is the characteristic of the intellect. It has to make the "I" a strong centre, a separate centre, otherwise no further evolution is possible. You may say that this looks like going downwards; nay, it is the germ of a new centre of life in which Divinity itself shall unfold when evolution is complete. There must be a clearly defined centre of consciousness, else how shall it work onward to perfection? And that centre grows by struggle. All strength comes by struggle of one kind or another. If you want your arms to become strong, it is no good to lie on a sofa and leave the muscles to grow merely by the nourishment that you give them. They want more than nourishment, they want exercise; and it is the law of all growth of form that the life must be drawn into the form, for only then can the form expand and become capable of receiving a further impulse of life; if the muscles are to grow, the cells that compose them must be stretched by exercise, and the life must flow into the expanded cell; only then does it become capable of multiplication, so that there may be many cells where before there was only one. The difference between the weak man and the strong man, the man who is feeble and the man who is athletic, is the difference brought about by exercise and struggle, by pulling against resistance, by taking up a weight and whirling it round and making the muscles strain against the weight. That is a picture of the way in which all life is working for development of form; the impulse of life leads to the exercise of the form, the exercise makes it plastic and increases the form, through which the life is thus enabled to flow more largely. That is as true in the mental world as in the physical world; for the mental world is also a world of phenomena. It is not the One; its characteristic is diversity, each being standing by himself, and regarding other things as separate. I know an object. How?
