A holy relationship is a common state of mind.  It says right there in the book.

It also says er er about illusion and er er that form is illusion, and it made me think again of illusionists, of what is possible to see and do, all merely by thinking of it.  Installing with the scaffold in the studio yesterday I felt like the illusionist’s assistant, in my tarty boots, up and down the scaffold through the trap door, crouching and catching myself on faith alone in the dark on the ladder.

Of course I never imagined the optics, I only heard them calling, did you look in there love!  at the wheels!  That the grid makes in the lens!  I colored them orange, right on my studio wall.
