he Yogis possess great knowledge regarding the use and abuse of
the reproductive principle in both sexes. Some hints of this esoteric
knowledge have filtered out and have been used by Western writers on
the subject, and much good has been accomplished in this way. In this
little book we cannot do more than touch upon the subject, and omitting
all except a bare mention of theory, we will give a practical breathing
exercise whereby the student will be enabled to transmute the
re-productive energy into vitality for the entire system, instead of
dissipating and wasting it in lustful indulgence in or out of the
marriage relations. The reproductive energy is creative energy, and may
be taken up by the system and transmuted into strength and vitality, thus
serving the purpose of regeneration instead of generation. If the young
men of the Western world understood these underlying principles they
would be saved much misery and unhappiness in after years, and would be
stronger mentally, morally and physically.

This transmutation of the reproductive energy gives more vitality to
those practising it. They will be filled with great vital force, which
will radiate from them and will manifest in what has been called
"personal magnetism." The energy thus transmuted may be turned into new
channels and used to great advantage. Nature has condensed one of its
most powerful manifestations of prana into productive energy, as its
purpose is to create. The greatest amount of vital force is concentrated
in the smallest area. The re-productive organism is the most powerful
storage factory in animal life, and its force can be drawn upward and
used, as well as expended in the ordinary functions of reproduction, or
wasted in vicious lust. The majority of our students know something of
the theories of regeneration, and we can do little more than to state the
above facts, without attempting to prove them.

The Yogi exercise for transmuting re-productive energy is simple. It is
coupled with rhythmic breathing, and can be easily performed. It may be
practised at any time, but is especially recommended when one feels the
instinct more strongly, at which time the re-productive energy is
manifesting and may be most easily transmuted for regenerative purpose.
The exercise is as follows:--

Keep the mind fixed on the idea of energy, and away from ordinary
sexual thoughts and imaginings. If these thoughts come into the mind
do not be discouraged, but reg
