This leveling is not recommended for beginners!
You can use any FSC, but in a passive state (without opening channels). You will need 9 or more Functional State Correctors.
First, two Correctors must be combined, as described in Pumping the spine with two FSCs. These devices should be placed under the coccyx and under the cervical spine along the body. Lie on your back on these two Correctors, place the rest on top of all 9 energy centers, across the body.
Gradually increase the pumping time, from 2 to 20 minutes.
