Energetically, the earth takes from you everything you don’t need. When you don’t have a good earth connection, you aren’t able to discriminate waste material from nourishing material.
As with any electric device that’s unearthed, the energy isn’t able to go through you, into the earth. Instead, it goes into whatever is nearest to you, causing all kinds of problems.
The solution is to put your awareness into your feet, to allow your awareness to go through your feet and into the earth.
This is known as finding your feet.
