All fingers and thumbs are simple keys to harmonize our attitudes. Mary differentiates 5 types of attitudes: worry😰, fear 😱, anger 😤, sadness 😭 and trying to 🤡. Worry is assigned to the thumb.
Worries pull us away from the present and dissipate our energies.
The thumbs are like leaders in a parade. If the thumb is not in rhythm, then all that follow the leader will get out of step, out of harmony. Thumbs are very important for the harmonious functioning of the body (Self-Help Book 3 by Mary Burmeister, p. 27).
By holding our thumbs we can release worries and brooding. It can also help with depression and eliminate the imbalance of our stomach and spleen function energy. If we harmonize our stomach and spleen function energy, we calm our nervous system. Babies who suck their thumbs try already to help their imbalances.
Just take your left thumb with your right hand and vice versa. This can be held for as long as you like.
Have fun practicing Jin Shin Jyutsu!
