The whole preparation is one movement of consciousness readying itself for a surrender of the lower self. The ass is the animal body, the beast of burden that carries a person's weight, and saddling it means bringing the flesh under command so it can be directed rather than obeyed. The 2 young men are the pair of lower faculties that go partway and then wait behind, since the highest work is done past the point where the ordinary powers can follow. Isaac, whose name holds laughter, is the beloved inner joy, the very thing a person is asked to lay down. The wood is split and carried because the fuel of the offering, the dense material substance, must be prepared by the one making it.
Rising early in the morning is awareness waking before the noise of the day, moving in the fresh light toward the appointed place, the raised center in the head where the offering is made. This is a person setting out, fully deliberate, to give up the dearest thing the lower life has produced.

2 young men: the pair of lower faculties that accompany the work partway and wait behind where they cannot follow.
Isaac: the beloved inner joy and laughter, the dearest fruit of the self that is brought to be surrendered.
Wood for the burnt offering: the dense material fuel that must be split and carried before the lower self can be given up.
The place: the raised center in the head, the appointed high point where the offering is made.
