A gift from Yoga: a specific hand position to smooth out your abilities to communicate clearly. Bring the tip of your thumb to the tip of your pinkie finger and press the tips together gently yet firmly (with about five pounds of pressure). Engage both hands, or instead just one. The Buddhi Mudra brings together Earth energy and our Positive Ego (the part of us that seeks connection and cooperation) and Mercury energy – our ability to communicate with self and others – with the flowing element of water. The Buddhi Mudra is renowned for providing mental clarity.

You don’t need to believe this (or any of what I’m including here.) Simply try it and experience for yourself.
