"Every fact and process in Nature contains a moral lesson for the wise man. There is no law in the world of Nature around us which is not to be found operating with the same mathematical certainty in the mind of man and in human life. All the parables of Jesus are illustrative of this truth, and are drawn from the simple facts of Nature. There is a process of seed-sowing in the mind and life a spiritual sowing which leads to a harvest according to the kind of seed sown. Thoughts, words, and acts are seeds sown, and, by the inviolable law of things, they produce after their kind."
