tion published by the Yogi Publication Society, which was
compiled and adapted by the writer of these lessons. In that edition of
the "_Bhagavad Gita_," on page 77, you will find these words attributed
to _Krishna_, the Absolute One in human incarnation:

"The worlds and universes--yea, even the world of Brahm, a single day
of which is like unto a thousand _Yugas_ (four billion years of the
earth), and his night as much--these worlds must come and go... The
Days of Brahm are succeeded by the Nights of Brahm. In these Brahmic
Days all things emerge from invisibility, and become visible. And, on
the coming of the Brahmic Night, all visible things again melt into
invisibility. The Universe having once existed, melteth away; and lo!
is again re-created."

And, in the same edition, on page 80, we find these words, attributed
to the same speaker:

"At the end of a _Kalpa_--a Day of Brahm--a period of Creative
Activity--I withdraw into my nature, all things and beings. And, at the
beginning of another _Kalpa_, I emanate all things and beings, and
re-perform my creative act."

We may say here, in passing, that Modern Science now holds to the
theory of periods of Rhythmic Change; of Rise and Fall; of Evolution
and Dissolution.

It holds that, beginning at some time in the past aeons of time, there
was the beginning of an upward or evolutionary movement, which is now
under way; and that, according to the law of Nature, there must come a
time when the highest point will be reached, and then will come the
beginning of the downward path, which in time must come to an end,
being succeeded by a long period of inactivity, which will then be
followed by the beginning of a new period of Creative Activity and
Evolution--"a Day of Brahm."

This thought of this law of Rhythm, in its Universal form, has been
entertained by the thinkers of all times and races. Herbert Spencer
expressly held to it in his "First Principles," expressing it in many
ways akin to this: "Evolution must come to a close in complete
equilibrium or rest;" and again, "It is not inferable from the general
progress towards equilibrium, that a state of universal quiescence or
death will be reached; but that if a process of reasoning ends in that
conclusion, a further process of reasoning points to renewals of
activity and life;" and again, "Rhythm in the totality of
changes--alternate eras of evolution and dissolution." The Ancient
Western Philosophers also indulged
