The Secrets of Semen Retention 139
2. Some people, if they have been collecting a lot of power this
way, might feel very hot and some might have an irritating feeling
to vomit or headache because the sexual energy is stuck in the head
of chest and the power is too great. This is a mild case of the
"Kundalini syndrome". The method mentioned of eating honey or
brushing the chest alone cannot solve the problem. You may have
to use running to burn the energy away, or other extensive exercises.
The energy should be disposed of in a non degenerative way.
Completing the Microcosmic Orbit is the most important safety
valve to help distribute the sexual energy evenly.
3. In the final stages of automatic mind control of sexual energy,
there is no need to clench the teeth, anus and buttocks. The whole
body stays relaxed and you contract not the buttocks but the front
urogenital diaphragm and the perineum only.
4. To more easily achieve the goal of automatic internal locking,
bear in mind you can do internal locking any time you want, driving
the car, sitting down, coffee or doing work. Practice contracting
the urogenital diaphragm, the contraction in front, not the buttocks.
Do this until you can fully control an erection or an urge to
ejaculate with a flicker of your mind.
