The 3 rising chambers of Solomon's house are the stations of the serpent force climbing the body, the winding-stair ascent told in stone. The lowest chamber, measured by 5, is the natural man of the 5 senses at the ground of the body, and the coiled energy is drawn upward from there until it reaches the third and highest chamber, the pineal at the crown, where the inner light is kindled.
The measurements are a code for consciousness, the same number 9 woven through the temple's whole design. This is what happens inside a living person when the force locked at the base of the spine climbs and lights the small chamber in the head.
Solomon's house: the human skull and brain, built to be the dwelling of the higher self
The nethermost chamber: the natural man of the 5 senses at the base of the body, where the rising force begins
The third chamber: the pineal gland at the crown, where the risen energy arrives and light is kindled
