Can someone explain what is accomplish in paragraph 6 of calypso borealis by john muir? and how does this paragraph illustrate naturalism?

oftentimes i had to sleep without blankets, and sometimes without supper, but usually i had no great difficulty in finding a loaf of bread here and there at the houses of the farmer settlers in the widely scattered clearings. with one of these large backwoods loaves i was able to wander many a long wild fertile mile in the forests and bogs, free as the winds, gathering plants, and glorying in god's abounding inexhaustible spiritual beauty bread. storms, thunderclouds, winds in the woods—were welcomed as friends.

The paragraph shows how Muir finds help for difficulties in nature. The allusion to naturalism can be perceived when the speaker relates nature to spirituality.

Explanation:

In the paragraph above we can see that Muir is going through a very difficult moment, where he feels hungry, tired and difficult to continue, however he finds strength and everything he needs to overcome his difficulties within nature. He accepts everything that nature gives, because he sees it as an inexhaustible source of wisdom, so if nature presents him with fruit he contemplates and thanks them, if nature presents him with storm he also contemplates and thanks.

He compares nature with the inexhaustible bread of spiritual beauty, which combines with the concepts defended in naturalism, where nature is portrayed as something powerful and closely linked to man's spirituality.
