Grounding is one of the most important tools you can learn about protecting your sacred space and your inner harmony.
Imagine you are standing on a hill with the sun directly over your head. Feel the air and feel the ground beneath your feet and know you are connected to both. Open up your crown chakra (the top of your head) and bring the light and the healing power of the sun (or universe) into your body. Let the healing power of eternal light and love wash throughout your body and vibrate with its energy, renewing and activating your own chakra energies. When you feel satisfied, extend this light/energy into the ground and let it reach down into the core of the earth like the root of a tree. Now bring that light up through your body and create a small sun in your solar plexus- that place where your ribs connect in your mid section. Make your own personal solar energy source- it can be any size that is comfortable to you. Know that all you have to do to re-energize your energy is to tap on your solar plexus, and your small internal sun will radiate all the energy that you need to sever negative energy. Continue this path of energy out of your head, and let it surround you so that it extends about 1-1 1/2' around your body. Take this light and make a shielding force. You may think of it as a cocoon of light or as a force shield. Wrap your entire being and outside aura in the power of this light. This shield of light will protect you from all invasions of negative energy and deflect them back to their source. Once you have received this shield of energy from the universe, you must return some of that energy so that it may ripple out of others. This can be done with a big exhalation of breath. Imagine the white/gold breath extending out like the ripples made by a stone dropped in a lake- only the lake is the entire universe.
