grounding vs earthing

alrighty, let me explain.

from what I hear people separate grounding and earthing. at least some people do.

the reasoning for this that I've heard is grounding is more metaphysical, you're bringing energy into your body, it's spiritual.

earthing however is a more physical way of doing it. you walk along the ground, grounding your mind and body in reality.

now, here's where I don't understand it. grounding and earthing both do almost the same thing when practiced. they both ground your body in this reality and help to silence any racing thoughts by grounding your mind as well. however, outside of grounding giving you energy for spell work to avoid burn out, I don't see much of a difference.

so that's what this is for. aside from ground being meta physical and earthing being physical, what is the difference between the two practices?
