Physical Body2

This progressive refinement of matter reflecting humanity's mental and spiritual evolution, will continue until, in the far distant future, the human encasement will be "relatively transparent, or diaphanous and luminous -- an ethereal body of actually condensed light" (ET 65).
The human body has "Manasic as well as Kamic organs," so that the cells answer to physical, mental, and spiritual impulses. The higher ego cannot act directly on the body, as its consciousness belongs to another plane of ideation; it has to act through its alter ego -- the personal self (BCW 12:368-9; or St in Oc 90-1). The inert physical body is built, cell for cell, upon the invisible substance of the astral model-body or linga-sarira. The latter contains the real organs of the senses and sensations, and it transmits the mental, emotional, and instinctual impulses to which the physical body reacts. The lower mind acts upon the physical organs and their cells; but only the higher mind can influence the atoms in these cells, and arouse the brain to a mental conception of spiritual ideas. That is to say, ideal, mental, and physiological wholeness depend upon the dominance of the atomic, spiritual impulses over the desires of the selfish kama-manasic nature. The personal nature is limited in action to the material, molecular cell. This subtle but practical interplay of his physical and superphysical nature points to the natural unity of purpose in the trend of ethics and physiology. With power to know good and evil, and free will to choose, man is responsible for refining and perfecting his material, personal nature into becoming a responsive and powerful medium for manifesting his spiritual and higher intellectual individuality.
