We have touched upon the subject of the cure of physical ailments in preceding pages.
(8) CONTROLLING THE EMOTIONS.
The undesirable emotions, such as Fear, Worry, Anxiety, Hate, Anger, Jealousy, Envy, Melancholy, Excitement, Grief, etc., are amenable to the control of the Will, and the Will is enabled to operate more easily in such cases if rhythmic breathing is practiced while the student is "willing." The following exercise has been found most effective by the Yogi students, although the advanced Yogi has but little need of it, as he has long since gotten rid of these undesirable mental qualities by growing spiritually beyond them.

The Yogi student, however, finds the exercise a great help to him while he is growing.
Breathe rhythmically, concentrating the attention upon the Solar Plexus, and sending to it the mental command "Get Out." Send the mental command firmly, just as you begin to exhale, and form the mental picture of the undesirable emotions being carried away with the exhaled breath.

Repeat seven times, and finish with the Cleansing Breath, and then see how good you feel.

The mental command must be given "in earnest," as trifling will not do the work.
(9) TRANSMUTATION OF THE REPRODUCTIVE ENERGY.
The 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.
