December 4:

December 4th. In the natural world we absorb heat, breathe air, draw on Environment all but automatically for meat and drink, for the nourishment of the senses, for mental stimulus, for all that, penetrating us from without, can prolong, enrich, and elevate life. But in the spiritual world we have all this to learn. We are new creatures, and even the bare living has to be acquired. Natural Law, p.267.
