The crumbs which clever minds tread underfoot

Those who have abandoned themselves to God always lead mysterious lives and receive from God exceptional and miraculous gifts by means of the most ordinary, natural and chance experiences in which there appears to be nothing unusual. The simplest sermon, the most banal conversations, the least erudite books become the source of knowledge and wisdom to these souls by virtue of God’s purpose. This is why they carefully pick up the crumbs which clever minds tread underfoot, for to them everything is precious and a source of enrichment.

This again is from Jean-Pierre de Caussade’s Abandonment to Divine Providence, as quoted by James Martin in The Jesuit Guide to (Almost) Everything: A Spirituality for Real Life.
