Chakras are psychic centres that lie along the axis of the spine as consciousness potentials. The chakras are not materially real and are to be understood as situated, not in the physical body, but in the subtle or etheric body. Repositories of psychic energies, they govern the whole condition of being.
These energy centers relate to seven energy fields. The chakras are said to be balanced if they are vibrating at the required frequency-open, bright and clean. When the chakra gets blocked, then it affects our physical and mental health. It is important to know and balance the energies of these chakras. When the chakras are open, a person is vibrant and healthy. By meditating on the chakras, one can work on increasing the flow of pranic energy into the body. Each of the main chakras corresponds to one of the elements of which the known world is compounded.
