of Creation, and each
act, either in accordance with the Divine purpose or the reverse, is
helping forward or retarding the completion of that Thought, though
like the cells we are ignorant of the end which Creation has in view.

In this life we seem indeed to be only, as it were, in embryo! The
study of embryology has lately shown us clearly how the clothing of
our Physical Ego has been formed, during the past millions of years,
from the lowest forms of life. Each one of us has, during what may be
called his lifetime, gone through all the different stages of
evolutionary development which, since the beginning of life on this
planet, have been employed to build up the human body in its present
form. Embryology has shown us that, during gestation, each human
embryo is a _replica_ of the past; it passes through the different
Imago stages from protoplasm to man, being unrecognisable at certain
stages from a monad, an amoeba, a fish with gills, a lizard, and a
monkey with a tail and dense clothing of hair over the whole body. The
human embryo has also, at an early stage, the thirteenth pair of ribs,
which is found in lower animals and is still seen in a rudimentary
form in anthropoid apes, but which disappears from the human embryo
before birth. Each generation, under evolutionary development, will
witness a further advancement in the clothing of the Physical Ego,
until it may be conceived that a hundred thousand years hence our
present stage of development will be seen only as one of the stages
through which the embryo has to pass before birth at that distant
time. May we not even glimpse at the future to which evolution is
carrying us? For in any of these stages we see organs forming whose
use only comes into play long after that stage has been passed; so
also, in the new rudimentary forms of thought which are started by
every fresh discovery may we not some day be able to descry the
heights which we are destined to attain if we earnestly seek after
Truth?

Radio-Activity has shown us that all forms of matter are but different
combinations of one primal brick; by synthesis thousands of new forms
of matter, unknown in Nature, are actually now being built up in our
laboratories, and the number of such combinations cannot conceivably
be limited; so do we also see that all the known forms of energy in
nature are interchangeable, one with another, with exactly known
equivalents and ratios, pointing to their being only differ
