This is a vast subject and basically untouched. Forming in the subconscious mind our astral blueprints are what determines the mental, physical, and spiritual structure of our physical body in our next incarnation. As the consciousness flows outward from the astral body drawn by magnetized sense attachments or abuses to matter, the delicate expression of original astral-blueprints become progressively more muddled and gross losing its true astral-design form, from distortion. The composition of the astral-blueprints animates the bodily processes of the physical body. Thus the creative power of the astral body thrusts itself into the physical form through several subtle centers in the body. The nineteen powers interwoven with the astral-blueprints are what maintain, enliven and build the gross physical form.
