In this excerpt from walden by henry david thoreau, what can be inferred about where transcendentalist thinkers searched for divinity?

every morning was a cheerful invitation to make my life of equal simplicity, and i may say innocence, with nature herself. i have been as sincere a worshipper of aurora as the greeks. i got up early and bathed in the pond; that was a religious exercise, and one of the best things which i did. they say that characters were engraven on the bathing tub of king tchingthang to this effect: "renew thyself completely each day; do it again, and again, and forever again." i can understand that. morning brings back the heroic ages. i was as much affected by the faint hum of a mosquito making its invisible and unimaginable tour through my apartment at earliest dawn, when i was sitting with door and windows open, as i could be by any trumpet that ever sang of fame. it was homer's requiem; itself an iliad and odyssey in the air, singing its own wrath and wanderings. there was something cosmical about it; a standing advertisement, till forbidden, of the everlasting vigor and fertility of the world. the morning, which is the most memorable season of the day, is the awakening hour.
