Chakras are energy wheels through which energy flows into or out of the body. When developed, they rotate as a wheel. The main chakras are seven. In fact, we have hundreds of chakras that are located out of the body. Each point of Acupuncture is an energy vortex and therefore – chakra. The energy that powers the wheels, comes from different sources – one of them is our own evolutionary Kundalini energy or another – the spiritual force within us. These energies spring from inside the body and flows through the energy wheels.
The chakras are not physical beings
Chakras Positioning
The chakras are associated with different states of consciousness, archetypal elements and philosophical constructs. The lower chakras as physically closer to the ground, are associated with more practical aspects of our life – survival, movement, action. They are controlled by physical and social laws. Upper energy wheels represent mental areas and act on a symbolic level through words, images and concepts. Each of the seven chakras presents one major area of human mental health, which briefly can be summarized as follows: (1) survival, (2) sexuality, (3) power, (4) love (5) communication (6) intuition and (7) knowledge.
