זוהר שמות — דף רי ע”א

From two openings descend two celestial chariots: the chariot of Michael, chief of the princes, and the chariot of Boel, the great appointee. These are two honored ministers who help in governing the world. They receive power from above and transmit it to those below. In a supernal secret they act as a chain of divine power from above to below. The holy chariots are the interfaces between the spiritual worlds and the physical world.
