Thoreau believes that nature, humans, and God are united and that God is found in everything in nature and in people. He believed that in order for humans to experience God within themselves, they needed to go and spend time in nature. There he finds solitude and peace, away from the people in the cities who want to own things and be rich. Thoreau feels the activity in the cities deprives us of our spirituality, and one must go back to the solitude of nature to get it back. Thoreau also believed that people don't need buildings and priests and books to know God since God is within each person. He wrote, "If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured or far away."
