But as man rises in the scale of consciousness he is able to disentangle his "Me" from his idea of body, and is able to think of his body as "belonging to" the mental part of him. But even then he is very apt to identify the "Me" entirely with the mental states, feelings, etc., which he feels to exist within him. He is very apt to consider these internal states as identical with himself, instead of their being simply "things" produced by some part of his mentality, and existing within him--of him, and in him, but still not "himself." He sees that he may change these internal states of feelings by all effort of will, and that he may produce a feeling or state of an exactly opposite nature, in the same way, and yet the same "Me" exists. And so after a while he is able to set aside these various mental states, emotions, feelings, habits, qualities, characteristics, and other personal mental belongings--he is able to set them aside in the "not-me" collection of curiosities and encumbrances, as well as valuable possessions. This requires much mental concentration and power of mental analysis on the part of the student. But still the task is possible for the advanced student, and even those not so far advanced are able to see, in the imagination, how the process may be performed. After this laying-aside process has been performed, the student will find himself in conscious possession of a "Self" which may be considered in its "I" and "Me" dual aspects. The "Me" will be felt to be a Something mental in which thoughts, ideas, emotions, feelings, and other mental states may be produced. It may be considered as the "mental womb," as the ancients styled it-capable of generating mental offspring. It reports to the consciousness as a "Me" with latent powers of creation and generation of mental progeny of all sorts and kinds. Its powers of creative energy are felt to be enormous. But still it seems to be conscious that it must receive some form of energy from either its "I" companion, or else from some other "I" ere it is able to bring into being its mental creations. This consciousness brings with it a realization of an enormous capacity for mental work and creative ability.
