y .... may be made to harden its particles to the
atmospheric changes. The whole secret is to succeed in evolving it out,
and separating it from the visible; and while its generally invisible
atoms proceed to concrete themselves into a compact mass, to gradually
get rid of the old particles of our visible frame so as to make them die
and disappear before the new set has had time to evolve and replace
them.... We can say no more.

A correct comprehension of the above scientific process will give a clue
to the esoteric meaning of meditation or contemplation. Science teaches
us that man changes his physical body continually, and this change is so
gradual that it is almost imperceptible. Why then should the case be
otherwise with the inner man? The latter too is developing and changing
atoms at every moment. And the attraction of these new sets of atoms
depends upon the Law of Affinity--the desires of the man drawing to his
bodily tenement only such particles as are necessary to give them
expression.

For Science shows that thought is dynamic, and the thought-force evolved
by nervous action expanding itself outwardly, must affect the molecular
relations of the physical man. The inner men, however sublimated their
organism may be, are still composed of actual, not hypothetical,
particles, and are still subject to the law that an "action" has a
tendency to repeat itself; a tendency to set up analogous action in the
grosser "shell" they are in contact with, and concealed within.--"The
Elixir of Life"

What is it the aspirant of Yog Vidya strives after if not to gain Mukti
by transferring himself gradually from the grosser to the next less
gross body, until all the veils of Maya being successively removed his
Atma becomes one with Paramatma? Does he suppose that this grand result
can be achieved by a two or four hours' contemplation? For the
remaining twenty or twenty-two hours that the devotee does not shut
himself up in his room for meditation is the process of the emission of
atoms and their replacement by others stopped? If not, then how does he
mean to attract all this time only those suited to his end? From the
above remarks it is evident that just as the physical body requires
incessant attention to prevent the entrance of a disease, so also the
inner man requires an unremitting watch, so that no conscious or
unconscious thought may attract atoms unsuited to its progress. This is
the real meaning of contemp
