Now you shall see the Temple completed:
After much striving, after many obstacles:
For the work of creation is never without travail;
The formed stone, the visible crucifix,
The dressed altar, the lifting light,
The visible reminder of Invisible Light.
...They followed the light and the shadow, and the light led them
forward to light and the shadow led them to darkness..
T.S. Eliot, 'Choruses from The Rock'
