Here is an exercise to keep cleanse the chakras. This is often necessary if you think of all the different energies which are floating around; all the negative energy worked up in an argument or by someone being horrible to you. All these things stay around you like a metal is attracted to a magnet.
Make sure you are relaxed, you can lie down or sit in a chair, then take some deep breaths.
Gradually sink down where you are, imagine your feet feeling relaxed and limp.
Imagine your legs doing the same, going up through your solar plexus and up to the base of your neck.
Let it go down your arms into your hands and to the very tips of your fingers, then go back to the base of your neck, let your shoulders go all limp, then up to the top of your head, now you should feel totally relaxed.
Visualise roots coming out of your feet, let them go into the ground, visualise them going to the very source of the earth's energy.
Visualise deep red energy and put your roots into it, then start drawing the energy up through your roots, like a tree does with water.
Then visualise a bright golden light above you, breath the light into your lungs, like glittering air.
Draw both of these energies into your groin, which is your ROOT chakra point. Visualise a RED disc, you should be able to see if it is dirty. Let these energies wash over it like a wave against cliffs, washing the dirt away. When you feel that it is done move to your STOMACH chakra, which is
Now imagine your aura see it all around you feel it look at all the colours swirling around, and if you feel or see any junk or dirt floating around get the red and golden energy to flush it out never to come back again. When you have finished that visualise your roots drawing back into you, do not worry about the energy that is left inside you, either store it or send it into them world.
