The mind tires in meditation and the hands grow heavy, the lifted attention beginning to sink, and what steadies it is the stone placed underneath. That stone is the pineal gland, and to sit upon it is to rest consciousness on that inner center where the energy is held; touching that seat in meditation releases the current that keeps the whole effort from failing. On either side the illuminating light and its support hold the hands up, so the raised attention stays firm and unwavering. The steadiness lasts until the going down of the sun, until the inner light within completes its work.
The battle below is won by what happens above: attention set upon the pineal stone and held steady on both sides lets the inner light burn on until sundown, so the flagging mind is carried through by resting on that still center rather than by straining.
Stone: the pineal gland, the inner seat consciousness rests upon to release its steadying energy
Moses: the mind itself, whose lifted attention tires and must be supported
Aaron: the illuminator, the inner light that holds the raised attention up on one side
The sun: the Christ, the inner light whose setting marks the completion of the work
