To the question, if the mind has a form, it may be answered, that the mind has the same form as that with which the soul is most impressed. And what is the form with which the soul is most impressed? One's own. That is why, when man says "I", he identifies himself with the form which is most impressed upon his mind, and that is his own. But the mind is a world within itself, a magic world, a world which can be very easily changed, very quickly altered, compared with the physical one. The phenomenon of the mind is great, and wonders could be performed if only one had the key of the mind in one's hand. The difficulty is that man becomes so fixed in his physical body, that he hardly realizes in life that he has a mind. What man knows of himself is of the body, through the mind; verily man is his own mind.
