In this way, then, our intuition is related to our imagination, and this
relation has its physiological correspondence in the circulus of molecular
vibrations I have described above, which, having its commencement in the
higher or "ideal" portion of the brain flows through the voluntary nervous
system, the physical channel of objective mind, returning through the
sympathetic system, the physical channel of subjective mind, thus
completing the circuit and being then restored to the frontal brain, where
it is consciously modelled into clear-cut forms suited to a specific
purpose.

In all this the power of the will as regulating the action both of the
intuition and the imagination must never be lost sight of, for without such
a central controlling power we should lose all sense of individuality; and
hence the ultimate aim of the evolutionary process is to evolve individual
wills actuated by such beneficence and enlightenment as shall make them
fitting vehicles for the outflowing of the Supreme Spirit, which has
hitherto created cosmically, and can now carry on the creative process to
its highest stages only through conscious union with the individual; for
this is the only possible solution of the great problem, How can the
Universal Mind act in all its fulness upon the plane of the individual and
particular?

This is the ultimate of evolution, and the successful evolution of the
individual depends on his recognizing this ultimate and working towards it;
and therefore this should be the great end of our studies. There is a
correspondence in the constitution of the body to the faculties of the
soul, and there is a similar correspondence in the faculties of the soul to
the power of the All-originating Spirit; and as in all other adaptations of
specific vehicles so also here, we can never correctly understand the
