"Qian ☰ and Kun ☷ are the door and the gate of change, the father and the mother of all hexagrams. Kan ☵ and Li ☲ are the inner and the outer walls, they spin the hub and align the axle. . . ."

"Know the white, keep to the black, and the Numinous Light will come of its own. White is the essence of Metal, Black the foundation of Water. . . ."
"The Lovely Maid of the River is numinous and supremely divine: when she finds Fire she flies away, leaving behind not a speck of dust. . . ."
