via Matt P. Vaguely apposite quote:
At Regensburg he crossed the Danube on his cloak, and there made a broken glass whole again; and, in the house of a wheelwright too mean to spare the kindling, lit a fire with icicles. This story of the burning of the frozen substance of life has, of late, meant much to me, and I wonder now whether inner coldness and desolation may not be the pre-condition for making the world believe, by a kind of fraudulent showmanship, that one’s own wretched heart is still aglow.
