When Chakras are out of balance they can affect the way you both feel and act.  A simple meditation will help keep them aligned.

When using crystals to cleanse chakras, lie on the floor and place the crystal on the corresponding chakra point, imagine a healing light from the crystal down to the chakra point. Totally relax and let the crystal do it's work.

Don't forget to cleanse and activate the crystals before you start your cleansing and also afterwards.

To meditate into your Chakras without using crystals simple lie on the floor, relax and aim to visualise all your Charkras as coloured orbs of the same size. Check each one and if you sense any black spots in or around the orb visualise these spots disappearing. Once you have cleansed all the chakras and checked they are in a straight line, any that you feel are out of line simply concentrate on that one until you feel it drop back into place.
