With grounding or centering we mean being firmly present in your body and cleaning it from lower frequencies, so that you can easily make contact with your intuition and unconsciousness knowledge.
How to ground yourself.
Find a relaxed posture; sitting right-up in lotus posture (meditation posture) is very suitable, but sitting right-up on a chair, or lying on your back on the ground can also work very good. Find out what suits you best. Close your eyes and release the tension in your muscles. Observe your breath for some moments try to breathe deeply and calmly, but don't force anything. If you don't manage to bring your breath downwards, simply accept that and try it another time.
Then visualize, or imagine, a transparant white lightbeam coming from above, entering your head at the crown-chakra (the energy centre at the top of your head). The white light fills up the upper part of your head, goes down to the 6th chakra between your eyes, and fills up the rest of your head with sparkling white light. On its way down along the spine the energy fills your throatchakra and shoulders with white light, your arms, your heart region and chest, your belly and the intestines, the hips, your inward and outward sexual organs, and your legs down to the feet. You must now clearly feel your feet. While the white light fills up your body darkness and negativity (being negative emotions and beliefs about ourselves, and problems/emotions of others we have absorbed in our energy system) are driven out. It can be very helpful to let your breath follow the cleansing white light, supporting the removal of dark energies. You may feel a temporary discomfort, an emotion coming up, or feel pain somewhere. Simply notice it, let it be as it is, breathe towards it, and after a while it will usually disappear. It may be part of your cleansing process.
The 'psychic dirt' of the body parts that are surrounded by air will simply dissolve into the air; where your body connects with the ground the 'dirt' will disappear into the ground. This last psychic dirt will be the thickest, since it represents fears and feelings of unworthiness. Imagine it on its way down to the center of Mother Earth, where it will be transformed through fluid fire and returned to you as clean energy in any color your unconsciousness wishes to show you. This color represents an energy-form you need more of.
So now you are experiencing two streams of energy along your spine, one upward and one downward. This is what is symbolized by the wand of Mercury (the caduceus): the wand is a representation of the invisible tube along the inside of our spine through which life energy is transported, and the two winding snakes depict the downward and upward energy streams from heaven and earth. It is possible to physically experience the energy as warmth, tickling energy along your spine, or shivering. Grounding makes you mentally and emotionally peaceful and concentrated. You will feel present and ready for the things you choose to do.
Remember the color(s) of the earth energy and open your eyes. You can wear clothes in the color you saw, buy flowers in it, visualize it regularly through the day, whatever you choose.
