one other aspect of grounding...the strength of my grounding, is relative to the level of energy I can bring in and hold.
Also, if you ground everyday, your emotions will tend to be more stable. It is less likely that you will get lost in the shuffle, so to speak. You are grounding in yourself too.
When you ground, you create a location, from which to "align" with things. It positions you in the universe. You also can bring energy to the earth, from heaven. The big yin /yang miX. The energy you put into the earth, doesn't only have to be that extra energy you are getting rid of. or worse,,, pollution...as a yin, or recessive being, the Earth takes this in. She does have the ability to heal herself. Doing positive work, like healing work, or sending her energy, softens the side effects to physical changes that can happen when she comes to a point where she "needs" to heal, due to excessive negative energy. Big picture perspective. Positive and negative energy. All our good work counts. I apologize for the side tracks. I hope I have inspired you to ground, and, give back to the earth for her healing.
