One is the beginning, the god-sun.
Two is Eros; for he bindeth twain together and outspreadeth himself in brightness.
Three is the Tree of Life, for it filleth space with bodily forms.
Four is the devil, for he openeth all that is closed. All that is formed of bodily nature doth he dissolve; he is the destroyer in whom everything is brought to nothing.
— Carl Jung, from Seven Sermons to the Dead
