Chakras are subtle energy points, literally called wheels of energy. They function as places of energy exchange. In fact, we have hundreds of chakra points spread over our subtle energy system. The best known, however, are the seven main chakras that are ethereally connected in the central energy channel of our body that runs along our spinal column. If the chakras function properly, these centers are gates for vital life energy that enter our bodies through our subtle bodies through channels (nadis) and meridians. But at the same time they are also escape points for lower frequency energy to flow back to the subtle bodies to be transformed. Each of the seven main chakras represents a level of consciousness or development phase of life, seen from the perspective of our physical existence. When the chakras are open and in balance, they form an integrated system, in which each chakra depends on the others for optimal functioning. Chakras can function less if they are in a negative state for longer periods of time due to negative habits and accumulated emotions. That makes it difficult for the personality to fully integrate the level of consciousness that each chakra represents.
