Definition - What does Vajroli Mudra mean?
Vajroli mudra is a yogic practice of strengthening the genital or urinary muscles in order to redirect sexual energy up the spine to other chakras. From Sanskrit, vajroli is derived from the root word, vajra, meaning "thunderbolt" and “lightning,” and mudra means "gesture," "mark" or "seal." This ancient practice is thought to preserve and use sexual energy to activate other chakras and awaken kundalini.
Yogis with a spiritual practice incorporate vajroli mudra to achieve enlightenment by harnessing energy to send to other chakras.
Yogapedia explains Vajroli Mudra
To practice vajroli mudra, engage the three bandhas (energy locks) while siting in padmasana or another comfortable seated pose. Constrict the muscles around the urethra, inhaling and exhaling up to 10 times. While constricting, focus on drawing energy up the spine and redirecting it to other chakras.
In addition to harnessing and redirecting sexual energy, the vajroli mudra is practiced by males to combat impotence or premature ejaculation. It is believed that with routine practice, semen can be redirected back into the body to cultivate and store sexual energy.
In a Tantric practice, withholding sexual energy from being released can cause the negative and positive poles of energy within an individual to unite in the body.
