This widely popular grounding technique is the one where you imagine roots coming out of your feet and going down into the earth. In other words you project a small part of your awareness through your feet down into the earth, as deep as you deem necessary, and secure it there with an image of your choosing; it could be tree roots, a garden hose, a rainbow, a waterfall or anything else. Then you pull up the earth energy into your system from the feet all the way to your head. Then you open your crown chakra and pull down universal energy all the way from your head to your feet. Then you set your intent for the energies to meet at the heart and stabilize. This is actually a Healing Touch style earth and universal energy distribution technique. Grounding is just the first part, where you create cords to release energy from your aura.
