Every walk to the woods is a religious rite, every bath in the stream is a saving ordinance. Communion service is at all hours, and the bread and wine are from the heart and marrow of Mother Earth. There are no heretics in Nature's church; all are believers, all are communicants. The beauty of natural religion is that you have it all the time; you do not have to seek it afar off in myths and legends, in catacombs, in garbled texts, in miracles of dead saints or wine-bibbing friars. It is of today; it is now and here; it is everywhere.

Blessed is the man who has some congenial work, some occupation in which he can put his heart, and which affords a complete outlet to all the forces there are in him.

....success in walking is not to let your right foot know what your left foot doeth. Your heart must furnish such music that in keeping time to it your feet will carry you around the globe without knowing it.

Nature teaches more than she preaches. There are no sermons in stones. It is easier to get a spark out of a stone than a moral.

The deeper our insight into the methods of nature . . . the more incredible the popular Christianity seems to us.
