The name Venus Lock is derived from the connection between the negative and positive sides of the Venus mounds. These are located on each hand and are the fleshy areas at the base of the thumb (which represents ego).
Venus represents sensuality and sexuality. This Mudra channels the sexual energy while balancing the glandular system. If you place both hands in this Mudra on your lap, you will be able to concentrate better.
This Mudra is done by interlacing the fingers. For women the right pinky stays on the bottom, while for men, it's the left. One of the thumbs touches the fleshy part between the other thumb and the index finger.
