new spiritual powers are to be revealed.

At this point may come a word of explanation. I have been asked why
I use the word Sutras, for these rules of Patanjali's system, when the
word Aphorism has been connected with them in our minds fora
generation. The reason is this: the name Aphorism suggests, to me at
least, a pithy sentence of very general application; a piece of
proverbial wisdom that may be quoted in a good many sets of
circumstance, and which will almost bear on its face the evidence of
its truth. But with a Sutra the case is different. It comes from the same
root as the word "sew," and means, indeed, a thread, suggesting,
therefore, a close knit, consecutive chain of argument. Not only has
each Sutra a definite place in the system, but further, taken out of this
place, it will be almost meaningless, and will by no means be
self-evident. So I have thought best to adhere to the original word.
The Sutras of Patanjali are as closely knit together, as dependent on
each other, as the propositions of Euclid, and can no more be taken
out of their proper setting.

In the second part of the first book, the problem of the emergence of
the spiritual man is further dealt with. We are led to the consideration
of the barriers to his emergence, of the overcoming of the barriers,
and of certain steps and stages in the ascent from the ordinary
consciousness of practical life, to the finer, deeper, radiant
consciousness of the spiritual man.
