Apergy? That was that the 'square of the times are as the cubes
of the distance.' It has lain fallow for centuries. No one of
your western physicists has ever studied it, or tried to explain
it. It remains just where Kepler left it, as the mere law of
orbital revolution of the planets only.

"It is the key to the proper understanding of the universe.

"'The squares of the times are as the cubes of the distance'
means that all motion is the result of two forces acting upon
prakriti, and that where the two forces are balanced, or equal,
the result in motion is a circle or ellipse, the square of the
Repulsion being equal to the cube of the Attraction to make them
equal and produce a circle. In other cases they produce
hyperbola and parabola.

"This is a little dry--nearly all fundamental knowledge is--but
the reward of patience is great.

"The orbital speed of the earth is about 60,000 miles per hour.
The attraction of the sun exactly equals the repulsion created by
the motion; more accurately, the speed created by the repulsion.
The result of the two forces working together at exact balance is
a circle. An ellipse is a circle bent a little, and the ellipse
in which the earth actually moves comes from varying attraction
and repulsion. Kepler's second law covers that.

"If the orbital speed of the earth were a mile less per hour, or
even a foot less, then the earth would wind up around the sun as
a dog gets wound up with his chain around a tree. If this speed
