So, here's a sample entry in Philip Pullman's intriguing little book THE IMAGINATION CHAMBER I wanted to share. I've broken up the lines to make for easier reading. --JDR
Mr Taphouse said one day as he ran his hand
over a freshly-planed length of oak:
"Feel that, boy, feel how old that is," Malcolm tried,
but all he could actually feel was the glassy smoothness
of the bare surface.
So he imagined it: acorn, sapling, mature tree,
a mighty canopy in the summer and a gaunt skeleton
in winter. From then on whenever Malcolm had
a piece of oak in his hands, or walnut, or even
simple honest pine, he liked to think of the tree it had been.
He liked to feel the immense age of it, visible
in the growth rings, and the past of it, and the
future too, as he thought of the acorns and walnuts
and pine cones. He imagined it. He pretended
he could see it.
From somewhere he remembered the expression
"the mind's eye". He imagined it, and thus he came
to see it, every time, until it became second nature . . .
