casioned by the relation
of that subject to the use of the mind in certain directions as will
appear fully later on.

In order to let you know that we are not advancing some peculiar theory
of the Yogis, which may not be in harmony with modern Western Science, we
give you in this article a number of quotations, from Western writers and
thinkers, touching upon this important faculty of the mind, so that you
may see that the West and East agree upon this main point, however
different may be their explanations of the fact, or their use of the
power gained by the cultivation of Attention.

As we said in our last lesson, the word Attention is derived from two
Latin words "_ad tendere_," meaning "to stretch toward," which is really
what Attention is. The "I" wills that the mind be focused on some
particular object or thing, and the mind obeys and "stretches toward"
that object or thing, focusing its entire energy upon it, observing every
detail, dissecting, analyzing, consciously and sub-consciously, drawing
to itself every possible bit of information regarding it, both from
within and from without. We cannot lay too much stress upon the
acquirement of this great faculty, or rather, the development of it, for
it is necessary for the intelligent study of _Raja Yoga_.

In order to bring out the importance of the subject, suppose we start in
by actually giving our Attention to the subject of Attention, and see how
much more there is in it than we had thought. We shall be well repaid for
the amount of time and trouble expended upon it.

Attention has been defined as a focusing of consciousness, or, if one
prefers the form of expression, as "detention in consciousness." In the
first case, we may liken it to the action of the sun-glass through which
the sun's rays are concentrated upon an object, the result being that the
heat is gathered together at a small given point, the intensity of the
same being raised many degrees until the heat is sufficient to burn a
piece of wood, or evaporate water. If the rays were not focused, the same
rays and heat would have been scattered over a large surface, and the
effect and power lessened. And so it is with the mind. If it is allowed
to scatter itself over the entire field of a subject, it will exert but
little power and the results will be weak. But if it is passed through
the sun-glass of attention, and focused first over one part, and then
over another, and so on, the matter may be maste
