Annie Dillard said this quote

The secret of seeing is, then the pearl of great price. If I thought he could teach me to find it and keep it forever I would stagger barefoot across a hundred deserts after any lunatic at all. But although the pearl may be found, it may not be sought. The literature of illumination reveals this above all: although it comes to those who wait for it, it is always, even to the most practiced and adept, a gift and a total surprise. I return from one walk knowing where the killdeer nests in the field by the creek and the hour the laurel blooms. I return form the same walk a day later scarcely knowing my own name. Litanies hum in my ears; my tongue flaps in my mouth. Ailinon, alleluia!
