We live in a world that has disconnected us from our ground to the point that our bodies cannot handle it anymore.
People use to connect with the Earth by living close to nature, doing rituals to thank our mother for hosting and feeding us, followed by regular dances and music gatherings around the fire.
This was healing in itself.
Now we spend a lot of our days in front of a screen, frenetically trying to connect with others virtually and spending time in connection with nature (and our nature) is barely part of our weekly schedule.
When we walk barefoot on the earth, we create an electric flow that counteracts the negative effects of electromagnetic waves, radioactive waves etc. Scientists even made of it a new technique of healing called "Earthing".
