ped
senses he possesses. He is able to distinguish the finest differences
in things, and his mind is so trained that, in thought, he may draw
conclusions from what he has perceived, in a manner that seems almost
"second-sight" to the uninitiated. _In fact, a certain degree of
second-sight is possible to one who develops his sense of Sight, under
the urge of Attention._ A new world is opened out to such a person. One
must learn to master the senses, not only in the direction of being
independent of and superior to their urgings, but also in the matter of
developing them to a high degree. The development of the physical senses,
also has much to do with the development of the "Astral Senses," of
which we have spoken in our "Fourteen Lessons," and of which we may have
more to say in the present series. The idea of _Raja Yoga_ is to render
the student the possessor of a highly developed Mind, with highly
developed instruments with which the mind may work.

In our future lessons we shall give the student many illustrations,
directions, and exercises calculated to develop the different faculties
of the mind--not only the ordinary faculties of everyday use, but others
hidden behind these familiar faculties and senses. Commencing with the
next lesson, we shall present a system of exercises, drills, etc., the
purpose of which will be the above mentioned development of the faculties
of the Mind.

In this lesson we shall not attempt to give specific exercises, but will
content ourselves with calling the attention of the student to a few
general rules underlying the development of Perception.

GENERAL RULES OF PERCEPTION.

The first thing to remember in acquiring the art of Perception is that
one should not attempt to perceive the whole of a complex thing or object
at the same time, or at once. One should consider the object in detail,
and then, by grouping the details, he will find that he has considered
the whole. Let us take the face of a person as a familiar object. If one
tries to perceive a face as a whole, he will find that he will meet with
a certain degree of failure, the impression being indistinct and cloudy,
it following, also, that the memory of that face will correspond with the
original perception.

But let the observer consider the face in detail, first the eyes, then
the nose, then the mouth, then the chin, then the hair, then the outline
of the face, the complexion, etc., and he will find that he will have
