““stood one day by the river on a dock where the ships came in, and all at once I found myself thinking, “If I can see a tree and cannot understand at all how it grows or why, how much less can I hope to understand the Cause of that tree? If I cannot understand why my mind gathers impressions and sorts and arranges them as it does, how can I hope to reach the Source from which my mind sprang?” This idea came to me with the accompaniment of a clear and sudden peace, as if someone had quietly spoken the answer to my long turmoil; and I knew that I believed in God.””
