In the fourth book, we are to consider what one might call the mechanism of salvation, the ideally simple
working of cosmic law which brings the spiritual man to birth, growth, and fullness of power, and prepares him for the splendid, toilsome further stages of his great journey home. While the path of progress in the gaining of Tranquility could not be traced thus far without reference to the freedom of a baby, a fuller consideration of what we may learn from this source must be of great use to us. The peace and freshness of a little baby are truly beautiful, but are rarely appreciated. Few of us have peace enough in ourselves to respond to these charms. It is like playing the softest melody upon a harp to those whose ears have long been closed. Let us halt, and watch, and listen, and see what we shall gain!
