This is a very short but powerful meditation. You can do this up to 11 minutes.

This gentle breath meditation brings the nervous and glandular systems into balance, tuning them to optimal efficiency. In this mudra, the thumbs are connected, which represent the energy of the ego. It was originally taught that this particular balance puts pressure on meridian points in the shoulders, relieving stress and balancing the nervous energies.
