The 7 stars and the 7 golden candlesticks are the 7 chakras, the 7 nerve centers strung up the spine from base to head, each a light burning at its station. Ephesus is the lowest of them, the sacrum at the base, where the work of raising the energy begins. The right hand that holds all 7 is the right hemisphere of the brain, the seat of the inner Christ; it is that side of the head, not any effort of will, that holds and charges the whole ladder of centers.
The one who walks in the midst of the candlesticks is the awakened power moving among these lights within a person, tending each center from the base of the spine to the crown.

Right hand: the right hemisphere of the brain, the seat of Christ consciousness, holding the centers
Ephesus: the sacrum at the base of the spine, the first center where the raising begins
