The Head Balance and Shoulderstand are unique asanas. They are two of the original Hatha Yoga poses. The goal of these two poses is not to have an affect on the body. They are mudras. A mudra is a position that we put the body in to have an affect on the nervous system, the energetic body. A mudra is sometimes called a seal too. Mudras act on energy the way a mirror acts on light. Energy that is normally moving down and out is turned back in and up.
The Head Balance and Shoulderstand are called viparita karani mudras, the reversing the flow mudras. The Head Balance is said to stimulate the pituitary gland, and the Shoulderstand stimulates the medulla oblongata and the vagus nerve.

They are also very powerful poses, like the King and Queen of a country.Read More
