The altar is built in the head, the seat in the skull where the offering is consumed, and the burnt offering is the inner energy rising from below to be spent upon the pineal, the same event the old calendars marked as the sun crossing into Aries at the spring festival. To build the altar and call upward is to gather that energy in stillness and direct it to the one high center where spirit does its work.
The answer comes as fire falling from the higher mind onto that altar, spirit descending into the head, not warmth kindled in the chest. When the current rises and the fire meets it, the offering is taken and the person is answered from within, in the very place where god is seen face to face.
Altar: the head, the seat in the skull where the inner offering is gathered and consumed
Burnt offering: the inner energy rising from below to be spent upon the pineal, the astronomical sun entering Aries at the spring crossing
Fire: spirit itself, descending from the higher mind into the head
Heaven: the higher mind, the seat of the awakened consciousness above
