Yoni-mudra gets its name yoni, meaning "uterus", because like the baby in the uterus, the practitioner has no external contact with the world and, therefore, no externalisation of consciousness. In Yoni Mudra yogis not only visualise each one of the chakras, but also listen intently to inner sounds or what is popularly called "the mystic sounds". The yoga texts say that if you are right-handed, you will hear these sounds in your right ear and if you are left-handed, you will hear these sounds in your left ear. The physical posture that is recommended is siddhasana because it is considered the best for sealing off the lower apertures. However, if siddhasana is not possible, one should try the padmasana. The yogi then seals all the upper apertures.

First, putting the thumbs in the ears close the ear holes. Keep your back straight.

Next close the eyelids and place the tips of the index fingers on them. If the eyeballs feel disturbed by the pressure of the finger on the eyelids, try drawing the eyelid down with the index fingers so that the only place where the fingers apply pressure is just below the eyes at the cheekbone.

The middle fingers push in on the nostrils. The ring fingers rest on the upper lip, while the little fingers rest under the lower lip.

Each elbow should be pointed outwards: the right at a ninety- degree angle to your right side, and the left elbow at a ninety-degree angle to your left side. Keep them in this position throughout and do not let them drop.

There are two variations in the technique of breathing while doing the Yoni Mudra. The first is simply to stop pinching the nostrils with your middle fingers when you wish to breathe in and out. In the other procedure, the nostrils are held tightly shut. The ring and little fingers stay put also, but the lips open as if you are pouting, or, as if you are about to whistle.
