in full harmony with the Will, that it may be brought to a focus and its
power greatly increased and its efficiency fully secured. Concentration
and Will-power are the means by which the Yogis obtain such wonderful
results, and by which they manage and direct their vigorous, healthy
minds, and master the material world, acting positively upon Energy and
Matter. This control extends to all planes of the Mind and the Yogis not
only control the Instinctive Mind, holding in subjection its lower
qualities and making use of its other parts, but they also develop and
enlarge the field of their Intellect and obtain from it wonderful
results. Even the Spiritual Mind is mastered, and aided in its
unfoldment, and urged to pass down into the field of consciousness some
of the wonderful secrets to be found within its area. By means of _Raja
Yoga_ many of the secrets of existence and Being--many of the Riddles of
the Universe--are answered and solved. And by it the latent powers
inherent in the constitution of Man are unfolded and brought into action.
Those highly advanced in the science are believed to have obtained such a
wonderful degree of power and control over the forces of the universe,
that they are as gods compared with the ordinary man.

_Raja Yoga_ teaches that not only may power of this kind be secured, but
that a wonderful field of Knowledge is opened out through its practice.
It holds that when the concentrated mind is focused upon thing or
subject, the true nature and inner meaning, of, and concerning, that
thing or subject will be brought to view. The concentrated mind passes
through the object or subject just as the X-Ray passes through a block of
wood, and the thing is seen by the "I" as it _is_--in truth--and not as
it had appeared before, imperfectly and erroneously. Not only may the
outside world be thus explored, but the mental ray may be turned inward,
and the secret places of the mind explored. When it is remembered that
the bit of mind that each man possesses, is like a drop of the ocean
