Nicos Kazantzakis, from his book The Saviors of God Spiritual Exercises,
A command rings out within me: “Dig! What do you see?”
“Men and birds, water and stones.”
“Dig deeper! What do you see?”
“Ideas and dreams, fantasies and lightning flashes!”
“Dig deeper! What do you see?”
“I see nothing! A mute Night, as thick as death. It must be death.”
“Dig deeper!”
“Ah! I cannot penetrate the dark partition! I hear voices and weeping. I hear the fluttering of wings on the other shore.”
“Don’t weep! Don’t weep! They are not on the other shore. The voices, the weeping, and the wings are your own heart.”
