Chakras are energy nodes, situated throughout the body, that are used to build and store energy in or to be opened to allow the flow of energy in making you more in tune with your astral or magickal self. There are in fact 8 Chakras in all. The first 7 are the more traditional ones but the last one is a new addition and can only be opened when all the other 7 are opened first. They are activated through meditation, by first sitting in your usual meditation position. Imagine energy flowing into your body and filling each one as you inhale. Chakra breathing is good for this which is breathing in for the count of four, holding for 7 and out for 8. On the four picture energy flowing into the chakra. On the 7 picture the energy swirling around the chakra and on the 8 imagine all the excess energy leaving the chakra. Do this until you feel that your chakra is open. It should only take a few cycles but go until you are ready. It also helps to do them in order from the lowest to the highest activating each one as you go up through your body.
For anyone who cant picture energy imagine two trails of light going through the body in a figure of 8 and up through the chakras, when it reaches the last one it goes straight down the back of the body and into the floor which grounds you. The paths are called the Ida and Pingala
