The force of repulsion created by the three higher notes of an
octave means just as much at the attraction created by the three
lower notes, whether it is in a chemical retort, within this
earth, or within this universe. The two forces balance, and are
exactly equal. They fight only within kinetic zones.

Given the vast manasic globe of differentiated matter, its atoms
uniting in different numbers to form molecules as the bases of
elementary substances, manasic substances, of course. The thrill
of vibration is sweeping through it from the spiritual plane
above, and the elements (and their combinations) which answer in
the lower notes gather and form a core, the Invisible Central
Sun, with its attraction. The elements answering in the higher
notes gather around it with their repulsion. So the two opposing
forces were born, with a vast kinetic skin for a battle-ground
between them.

The attraction of the invisible central sun manifests itself to
us in prakriti as Light. The repulsion of its covering, or the
higher static vibration of manasa, manifests itself to us as
Darkness. The first creative act in or on matter was the
creation of Light and its separation from the Darkness. The next
creative act was the establishment of a kinetic skin or zone
between them, a firmament in which the two forces of Light and
Darkness could strive for mastery. "And God called the firmament
Heaven." The third creative act was the gathering of the solids
and liquids together, and the beginning of the kinetic work in
the creation of forms and shapes, by the cross play of the two
forces in their combinations of solid with gases.
