James Finley is a former Trappist monk who, when he was a young monk, studied under Thomas Merton. In his book, Merton’s Palace of Nowhere, Finley recalls Merton telling him not to try so hard to pray:
He said, "How does an apple ripen? It just sits in the sun. A small green apple cannot ripen in one night by tightening all its muscles, squinting its eyes, and tightening its jaw in order to find itself the next morning miraculously large, red ripe, and juicy beside its small green counterparts. Like the birth of a baby or the opening of a rose, the birth of the true self takes place in God's time. We must wait for God, we must be awake; we must trust in God's hidden action within us.”
Okay, I'm not trying so hard. I'm just sitting in stillness, in His presence. There is nothing I can say to Him that He doesn't already know. I'm learning that the most powerful prayer of all is listening.
