Grounding has been in Torah long before the science was discovered.
Exodus 3.4 ….G-d called to him from the midst of the bush and said, “Moses, Moses!” And he said, “Here I am.”Then He said, “Do not draw near this place. Take your sandals off your feet, for the place where you stand is holy ground.”
I love going barefoot, love the feel of grass between my toes in the summer, and even the warm wood of our home in cooler months. Going barefoot doesn’t remind me of mourning; quite the opposite it makes me feel free, happy, and alive! So as long as it’s not actually a sin, I’m going to leave my shoes (and the dirt and germs they carry from concrete and building floors like grocery stores) at the door.
A great article was written in 2012 from PMC- US National Library of Medicine National Institutes of Health
