Each chakra has a certain number of points, the lower the amount of points the lower down the spine it is located. Points can also be known as ~petals~ because chakras are sometimes shown, or thought of, as being related to the lotus flower.
Each chakra has a purpose, whether it be mentaly, physically or spiritualy controling. It also controls a certain part of your body. Such as the uppermost chakra, , controls the top portion of your brain and your right eye.
Well, now you know that when a spell is talking about using chakras, you can think of them as little balls of energy in your spine! ~giggle~
