For a path to be a path, you have to be able to see it, or at least catch glimpses of it, every so often. And for that to happen, somebody needs to have walked it ahead of you. We [might] not be able to see them, but here and there they have left a sign: a shoe or a boot abandoned in the muck, something they have dropped, a pile of stones, a depression in the grass, a way marker inscribed with an arrow pointing the way – or simply the holiness of their lives.
–Br. James Koester, Society of St. John the Evangelist
