BlueMeenee, just visualize a circle opening and closing just like a film camera lense opening (remember those? lol), it has overlapping edges and the opening is smaller or larger depending on how the exposure is set. Sit comfortably in a chair, feet on the floor. Imagine the openings as small or as large as you want it and the earth energy coming up through the soles of your feet, up your legs, etc. You can stop it any time and imagine these chakras closing completely. It's called running energy and helps to keep us grounded. That's it!
Another way to get more grounded is to get outside and walk around in the dirt and nature, kick around in the leaves, breathe in the clean air. You'll feel energized as a result, a clearer head. The goal is to soak in the earth energy.
A good way to get all your chakras cleared out and 'awake', is to sit in a place where you won't be disturbed for about 30 minutes. Sit the same way, comfortably in a chair, eyes closed. Imagine each chakra at a time, beginning with your root or base chakra, ending with your crown chakra. It helps to also visualize the color associated with each one.
Open the chakra in the same way as the ones in your feet, except now the opening is as large as a dinner plate. See it spinning clockwise. Let the chakra spin for about a minute or however comfortable you are with it. The idea is to get the energy moving in each chakra and keep it flowing. Areas in which you feel clogged could be due to stagnant energy. Now, start closing the chakra, seeing the opening getting smaller. Decrease the opening to the size of a pencil eraser. You never want to close the chakras completely, since we use them every day and it would be like trying to walking around with your eyes closed! Imagine your chakras as always spinning; after all, they are energy and always working for you.
Go to the next chakra, which is your sacral and do the same exercise. Clear each chakra, ending with your crown at the top of your head. You will feel energized and relaxed at the end of this, and more balanced.
