The universe is a complex of many interrelated points such as suns and planets, in the same way the material and subtle bodies of the yogi–which reflect and react on one another–are a network of life energy points known as chakras.
Chakras are points in the bodies into which the universal life force (vishwaprana) flows. Without that constant inflow the bodies would become dormant and disintegrate–would die. The chakras are both entrances and exits for the cosmic life power as well as reservoirs of that power and points of intelligent direction of the power.
There are many subsidiary satellites of the chakras called adharas. Adharas are reservoirs of pranic energies, storage units for the energies that flow into the subtle bodies through the chakras, and therefore can be (and often are) mistaken for a chakra.
