13

Vibration Mudra

This practice encourages the development of sperm and, by extension, improves the quality of the libido. In fine-tuning the system that produces spermatozoa, there are two important considerations. First, the testicles should not be held too close to the body, where they become too hot and too compressed. The second consideration is movement. In order to encourage spermatogenesis, the testicles must be able to move. The Scots, in the old days, had good reason to wear nothing under their kilts. Many traditional peoples in the Americas, Africa, and Asia wore loincloths, which also allow the genitals to hang free.

This exercise creates both coolness and movement by gently jiggling the testicles. It thus facilitates sperm production and helps the spermatozoa move toward the prostate. Since this exercise also stimulates hormones, it will cause the man to become more virile.

The preceding two mudras—Exercises 12 and 13—should each be performed for at least three to four minutes each day, and can be repeated three or four times per day.

It is best to practice these mudras at night before going to bed, as they will help the kidneys and their libidinal energies regenerate while you sleep.

Whereas Exercise 12 should be practiced alone (although some fantasies may be permitted), Exercise 13 can be practiced (perhaps very enjoyably) with a partner, since the only important element is the testicular movement.
