Central Nervous System
The Central Nervous System and the Spinal Cord (vertical center channels) act as the control panel to every operation of function in the bio-computer. Every physical, mental, emotional and spiritual function is initiated at some level and managed by the neurological system. Therefore it is mandatory to energetically correct and upgrade the nervous system and Spinal Cord to be able to function at higher levels and to be able to receive the communication from our soul (spiritual layers of our nervous system).
