The watcher is the conscious observer inside a person, and watching is what turns the streaming waves of the cosmos into particles received through the pineal. That act of attention comes down from Uranus, the Greek heaven, the field of light overhead, and it fells the proud spine. The trunk is cut and the man drops back into his lower animal nature, feeding in the grass with the beasts, because the ruling mind that stood tall has been brought low.
What survives is the stump and its roots, banded in iron and brass, held in the earth of the ordinary mind until the process finishes. The number 7 is completion, so the wet, grazing exile lasts until a full cycle of change has passed over him and the operator wakes again.
Watcher: the conscious observer within, whose looking collapses the wave into the particle it receives
Tree: the spine, the standing trunk of the body that the ruling ego has climbed
Heaven: Uranus, the field of light above from which the higher current descends
Beasts of the field: the lower animal mind a person falls into when the higher rule is cut off
Earth: the ordinary mind, the ground the roots are kept in
7: completion, a full cycle turning until the change is finished
