"Advance, O people, with snow-white faces and radiant hearts, unto the blest and crimson Spot ..."

"The eye of My loving-kindness weepeth sore over you, inasmuch as ye have failed to recognize the One upon Whom ye have been calling in the daytime and in the night season, at even and at morn. Advance, O people, with snow-white faces and radiant hearts, unto the blest and crimson Spot, wherein the Sadratu’l-Muntahá is calling: ‘Verily, there is none other God beside Me, the Omnipotent Protector, the Self-Subsisting!’"

-Bahá'u'lláh, Proclamation of Bahá’u’lláh, p. 73
