“The Ministers of the temple of truth, it has been said, are of three kinds: first, those stationed at the gate of the temple to constrain the passers-by to come in; secondly, those whose function is to accompany inside all who have been persuaded to enter, and display and explain to them the treasures and secrets of the place; and, thirdly, those whose duty is to patrol round the temple, keeping watch and ward and defending the shrine from the attacks of enemies.
