JoyBoots Meditation for Clarity and Calm
It can sound mysterious and there are many traditions of meditation.
Experiment with this simple JoyBoots Meditation for Clarity and Calm that uses a segmented breath to engage your relaxation response. Rumination is interrupted by the intentional breath practice, focus of the eyes (activates the frontal lobe which regulates clear thinking) and mudra (hand position).
If you give it a try, let me know your experience.
