Purification of consciousness is shown by shaving the head, the old secret discipline of stripping away what covers the crown so the higher current can reach it. To take these others and cleanse alongside them is to bring the inner faculties through the same clearing, removing the growth that shadows the top of the skull where the divine enters. Keeping the law is not obedience to a code but living in accord with the fixed order of energy in the body, the current that runs true when nothing obstructs it.
The shaved head marks a person who has cleared the crown and walks in step with the inner order, so the whole system of the self runs orderly along the law that governs the flow of spirit.
