and then the objective mind, acting through the frontal brain --- the area of comparison and analysis --- proceeds to work upon a clearly perceived idea and to bring out the potentialities that are latent in it.

It must of course be borne in mind that I am here speaking of the mental ego in that mode of its existence with which we are most familiar, that is as clothed in flesh, though there may be much to say as to other modes of its activity. But for our daily life we have to consider ourselves as we are in that aspect of life, and from this point of view the physiological correspondence of the body to the action of the mind is an important item; and therefore, although we must always remember that the origin of ideas is purely mental, we must not forget that on the physical plane every mental action implies a corresponding molecular action in the brain and in the two-fold nervous system.

If, as the old Elizabethan poet says, "the soul is form, and doth the body make," then it is clear that the physical organism must be a mechanical arrangement as specially adapted for the use of the soul's powers as a steam-engine is for the power of steam; and it is the recognition of this reciprocity between the two that is the basis of all spiritual or mental healing, and therefore the study of this mechanical adaptation is an important branch of Mental Science.
