There are three steps to a successful chakra balancing meditation or technique:
First, you must clear each chakra of negative energy. Negativity is represented by a dirty, murky looking chakra. You must change the color of the chakra to the most brilliant shade you can imagine. Sprinkles of white can be mixed into any chakra to lighten the color to the shade you need.
Second, you must balance them. Similar to the tires on a car, chakras must be balanced to ensure proper alignment and direction. Each chakra should be rotating in a clockwise direction. This may mean that you stop a chakra from spinning and encourage it to reverse its direction.
Third, you must charge them by infusing them with energy. This is done by making the chakras larger or smaller so that each chakra is the same size. The meditation and slide show presented here will help you with these steps.
