Breathe with the sensations
There may be times that you are experiencing uncomfortable sensations with a strong intensity.
Your body may instinctively tense up against those sensations, but I invite you to explore another way. Let the sensations move through you, as if they were waves. Waves of sound. Waves of water (we are mostly water, after all).
Breathe.
Wiggle.
Sing Several of the Hemi-Sync mind training recordings I recommend have a humming or singing component that is particularly helpful at these moments.
Cry.
Remember that you are not your body.
