It is the place where power is generated and is considered the source of all things. [Usage function:] Lie down comfortably, spread your legs, and insert the larger part of the egg first. Just release it with your fingertip. Once it passes through the bladder opening, the yoni wall pulls the egg in. Eggs can be used during meditation, while sitting or working on a TV, or walking around during activities every day.
