The Soul of the Indian
"There were no temples or shrines among us save those of nature. Being a natural man, the Indian was intensely poetical. He would deem it sacrilege to build a house for Him who may be met face to face in the mysterious, shadowy aisles of the primeval forest, or on the sunlit bosom of virgin prairies, upon dizzy spires and pinnacles of naked rock, and yonder in the jeweled vault of the night sky! He who enrobes Himself in filmy veils of cloud......He needs no lesser cathedral!"
Charles Alexander Eastman (Ohiyesa) from the book The Soul of the Indian.
