Three symbols: the Word, ourselves, the world. We are here to recognize turning signs as such, to recognize one another, to recognize nature; and for the recreation of all three. To read any one truly is to read it through the other two.
Manifold appearances and myriad forms, and all spoken words, each should be turned and returned to oneself and made to turn freely.
