The dust of the streets is more precious than gold

Your enjoyment of the World is never right, till you so esteem it, that everything in it, is more your treasure than a King’s exchequer full of Gold and Silver. And that exchequer yours also in its place and service. Can you take too much joy in your Father’s works? He is Himself in everything. Some things are little on the outside, and rough and common, but I remember the time when the dust of the streets were as pleasing as Gold to my infant eyes, and now they are more precious to the eye of reason.

Thomas Traherne, Centuries 1.25.
