at is crude anatomy and crude physiology in
these sections, it is evident, however, that certain glimpses of truth
were perceived by the Rishis of ancient times. Verse 15 shows that the
great discovery of Harvey in modern times was known in ancient India.

560. In works on yoga it is laid down that the main duct should be
brought under the control of the will. The soul may then, by an act of
volition, be withdrawn from the whole physical system into the
convolutions of the brain in the head. The brain, in the language of
yogins, is a lot us of a thousand leaves. If the soul be withdrawn into
it, the living creature will then be liberated from the necessity of food
and sleep, etc., and will live on from age to age, absorbed in

561. It is often said that in an advanced stage of yoga, one is enabled

creation which we behold is the result of the penances of those sages who
were first created. Perhaps, what is intended to be said is that the
principle of life, of life proceeding from life, and primal matter with
space, etc., are all due to the fiat of God; while all visible and
tangible objects, resulting from the action of those principles and from
primal matter and space, are attributable to the ancient sages.

564. The word Ghrina may also mean aversion. Of course, here it would
mean, if used in that sense, aversion for all unrighteous acts.

565. The first half of the first line of 6 is differently read in the
Bombay edition. Both readings are noticed by Nilakantha. I have adhered
to the Bengal reading, though the Bombay reading is clearer in sense.
