What Are Chakra Systems?
Chakras are energy points in our etheral or subtle body. They are part of the etheral body, not the physical body, and as such they are the meeting points of etheral energy channels called nadis.
Nadis are channels in which the life force (prana) (non-physical) or vital energy flows. While there are several chakra systems in the body, only 7 are considered to be the most important.
In order for our bodies to function optimally, all 7 of the chakras need to be balanced, allowing our energy to flow smoothly throughout the body. If one energy center is not functioning well, the others do not function as well as they should. Some of them can even over compensate and work too hard or too much. This sends our bodies and emotions into a free-fall.
