“This earth, when it becomes purified and sanctified, or celestialized, will become like a sea of glass, and a person by looking into it can know things past, present, and to come; though none but celestialized beings can enjoy this privilege; they will look into the earth, and the things they desire to know will be exhibited to them, the same as the face is seen by looking into a mirror” (“Remarks,” Deseret News, Jul. 3, 1861, 137).
