The Chakras are multi dimensional energy centers.
There are many of them, located in different parts of our body, not only the physical but our subtle bodies such the Astral, the Mental and so on.
The most familiar and known chakras are the main seven centers that go up our spine and display the colors of the rainbow.
These energy centers are like "spiritual organs" necessary for our health and well-being in all aspects of our life.
