Also:A centering exercise (like before a meditation or a performance)

From the web site of the Reno Psychic Institute:

Grounding is the base of the spiritual pyramid
Grounding locates you in time and space.
Then you, the Being can know
Where you, the body is
Grounding allows you to release what is not you.
Then you can know what is you.
Grounding gets the energy in your aura moving
so you can create in present time.
Grounding creates space so you can be in your body.
