ide world. If he keeps these doors but half open, or crowded up with
obstacles and rubbish, he may expect to receive but few messages from
outside. But if he keeps his doorways clear, and clean, he will obtain
the best that is passing his way.

If one were born without sense-organs--no matter how good a Mind he might
have--he would be compelled to live his life in a dreamy plant-life stage
of existence, with little or no consciousness. The Mind would be like a
seed in the earth, that for some reason was prevented from growing.

One may object that the highest ideas do not come to us through the
senses, but the reply is that the things obtained through the senses are
the "raw material" upon which the mind works, and fashions the beautiful
things that it is able to produce in its highest stages. Just as is the
body dependent for growth upon the nourishment taken into it, so is the
mind dependent for growth upon the impressions received from the
Universe--and these impressions come largely through the senses. It may
be objected to that we know many things that we have not received through
our senses. But, does the objector include the impressions that came
through his senses in some previous existence, and which have been
impressed upon his instinctive mind, or soul-memory? It is true that
there are higher senses than those usually recognized, but Nature insists
upon one learning the lessons of the lower grades before attempting those
of the higher.

Do not forget that all that we know we have "worked for." There is
nothing that comes to the idler, or shirker. What we know is merely the
result of "stored-up accumulations of previous experience," as Lewes has
so well said.

So it will be seen that the Yogi idea that one should develop all parts
of the Mind is strictly correct, if one will take the trouble to examine
into the matter. A man sees and knows but very little of what is going
on about him. His limitations are great. His powers of vision report only
a few vibrations of light, while below and above the scale lie an
infinity of vibrations unknown to him. The same is true of the powers of
hearing, for only a comparatively small portion of the sound-waves reach
the Mind of Man--even some of the animals hear more than he does.

If a man had only one sense he would obtain but a one-sense idea of the
outside world. If another sense is added his knowledge is doubled. And so
on. The best proof of the relation between in
