The trees you planted in childhood have grown
too heavy. You cannot bring them along.
Give yourselves to the air, to what you cannot hold.
— Rainer Maria Rilke, from “Sonnet 4,” The Sonnets of Orpheus, in A Year with Rilke: Daily Readings from the Best of Rainer Maria Rilke, trans. & edited by Anita Barrows and Joanna Marcy (HarperOne, 2009)
