Scorpion pose tidbits

According to Swami Satyanandaji  the scorpion pose(only some facts that are not too well known about the pose is here:)

1. Reorganises prana around the body
2. Tones the uro-genital system
3. Stops the aging process
4. Rectifies glandular disorders
5. Is a ajna chakra pose (Third eye/intuition chakra)

Interestingly both the Iyengar book and Swami Satyanandaji's book are using the same words -- verbatim -- to describe how the scorpion pose is a pose of ego subjugation. I wonder who said it first, and if it is a translation from a major text... even so, word to word, the same description!
