“Thou shall see in it no hollows or rising hills.”

"The Bird of the Realm of Utterance voiceth continually this call: “All things have I willed for thee, and thee, too, for thine own sake.” If the learned and worldly-wise men of this age were to allow mankind to inhale the fragrance of fellowship and love, every understanding heart would apprehend the meaning of true liberty, and discover the secret of undisturbed peace and absolute composure. Were the earth to attain this station and be illumined with its light it could then be truly said of it: “Thou shall see in it no hollows or rising hills.”"
