"The prana does not then fill this material universe. There must
be yet another form of matter rarer and finer than prana, from
which prana is made, as ether is made from prana and prakriti
from ether. Have we any other class of phenomena to explain,
except vital and physical? Yes, there is a very important class,
mental. And here we have the explanation, if we exercise our
reason.

"These pranic globes are floating in an ocean of manasa, matter
in its rarest form.

"Each atom of prana is formed from manasa, exactly as ether was
formed from prana, and each pranic atom in the universe is the
centre of a manasic molecule, having an atmosphere of manasic
atoms.

"So we are not exact in giving the prakritic atom three planes or
octaves of vibration. It has four. You merely surround it with
etheric atoms, and this is correct so far as it goes. You only
wish to explain physical problems. But there are other problems
to be explained, problems of life and mind, and the same
knowledge you have explains them as well as the others, if you
simply avail yourself of it. That you do not consider the atom
as four-fold instead of two-fold is your own fault. I have not
told you anything you did not already know. I have only asked
you to apply your present knowledge of physics to these problems
of life and mind, and apply your reasoning powers.
