The number 7 is the count of the sacred centers strung up the spine, the ladder of energy that rises through a person from base to crown. The 7 stars are the inner intelligences that govern those centers, held in the right hand because the right is the side of conscious mastery, of the power a person can direct. The 7 candlesticks are those same centers seen as vessels that carry light, the bodily lamps waiting to be kindled. Star and candlestick are the same 7 read twice, once as living guidance above and once as burning column below.
The churches are not buildings and not congregations but the 7 energy centers within the body, each one a chamber of light along the inner column.
The number 7: the count of the sacred centers set along the spine, the full ladder of energy rising through a person
The 7 stars: the ruling intelligences of those centers, the inner lights that guide each stage of the ascent
The right hand: the side of conscious power and mastery, where what is grasped can be knowingly directed
The 7 candlesticks: the bodily centers seen as lamps, the vessels along the spine waiting to be lit
