limit of His field of activity, a vast sphere whose circumference is far
larger than the orbit of the outermost of His future planets. Within the
limit of that sphere He sets up a kind of gigantic vortex--a motion which
sweeps together all the bubbles into a vast central mass, the material of
the nebula that is to be.

Into this vast revolving sphere He sends forth successive impulses of
force, gathering together the bubbles into ever more and more complex
aggregations, and producing in this way seven gigantic interpenetrating
worlds of matter of different degrees of density, all concentric and all
occupying the same space.

Acting through His Third Aspect He sends forth into this stupendous sphere
the first of these impulses. It sets up all through the sphere a vast
number of tiny vortices, each of which draws into itself forty-nine
bubbles, and arranges them in a certain shape. These little groupings of
bubbles so formed are the atoms of the second of the interpenetrating
worlds. The whole number of the bubbles is not used in this way, sufficient
being left in the dissociated state to act as atoms for the first and
highest of these worlds. In due time comes the second impulse, which seizes
upon nearly all these forty-nine bubble-atoms (leaving only enough to
provide atoms for the second world), draws them back into itself and then,
throwing them out again, sets up among them vortices, each of which holds
within itself 2,401 bubbles (49^2). These form the atoms of the third
world. Again after a time comes a third impulse, which in the same way
seizes upon nearly all these 2,401 bubble-atoms, draws them back again into
their original form, and again throws them outward once more as the atoms
of the fourth world--each atom containing this time 49^{3} bubbles. This
process is repeated until the sixth of these successive impulses has built
the atom of the seventh or the lowest world--that atom containing 49^{6} of
