The house is the body, built in stories, and 1 does not enter the higher rooms straight on but by a turning, winding climb. The door opens on the right side, the way of active strength, and from there the ascent is gradual: first the middle chamber, then out of the middle into the third, never skipping a floor. This is how awareness rises in a person, level by level, each state opened only after the one below it has been passed through and closed. There is no leap to the top; the stairs wind because growth in a person turns back on itself before it climbs higher.
House: the body built in stories, the temple whose rooms are the rising levels of a person's awareness
Winding stairs: the turning, gradual climb by which awareness ascends, curving back on itself before reaching higher
Middle chamber: the intermediate state of consciousness, the room 1 must fully pass through before the next opens
Third: the higher room reached only in order, after the levels beneath it have been entered and left behind
