“Know, however, that the seeker, at the outset of his journey, witnesseth change and transformation, as hath already been mentioned. This is undoubtedly the truth, as hath been revealed concerning those days: “On the day when the earth shall be changed into another earth.” These are indeed days the like of which no mortal eye hath ever seen. Blessed is he that attaineth thereunto and realizeth their full worth.”

– Bahá’u’lláh, Gems of Divine Mysteries
