From Bahá’u’lláh
Arise, and proclaim unto the entire creation the tidings
that He Who is the All-Merciful hath directed His steps towards the Ridvan and
entered it. Guide, then, the people unto the garden of delight which God hath
made the Throne of His Paradise. We have chosen thee to be our most mighty
Trumpet, whose blast is to signalize the resurrection of all mankind.
Say: This is the Paradise on whose foliage the wine of utterance hath imprinted the testimony: "He that was hidden from the eyes of men is revealed, girded with sovereignty and power!" This is the Paradise, the rustling of whose leaves proclaims: "O ye that inhabit the heavens and the earth! There hath appeared what hath never previously appeared. He Who, from everlasting, had concealed His Face from the sight of creation is now come." From the whispering breeze that wafteth amidst its branches there cometh the cry: "He Who is the sovereign Lord of all is made manifest. The Kingdom is God's," while from its streaming waters can be heard the murmur: "All eyes are gladdened, for He Whom none hath beheld, Whose secret no one hath discovered, hath lifted the veil of glory, and uncovered the countenance of Beauty."
Within this Paradise, and from the heights of its loftiest chambers, the Maids of Heaven have cried out and shouted: "Rejoice, ye dwellers of the realms above, for the fingers of Him Who is the Ancient of Days are ringing, in the name of the All-Glorious, the Most Great Bell, in the midmost heart of the heavens. The hands of bounty have borne round the cup of everlasting life. Approach, and quaff your fill. Drink with healthy relish, O ye that are the very incarnations of longing, ye who are the embodiments of vehement desire!"
This is the Day whereon He Who is the Revealer of the names of God hath stepped out of the Tabernacle of glory, and proclaimed unto all who are in the heavens and all who are on the earth: "Put away the cups of Paradise and all the life-giving waters they contain, for lo, the people of Baha have entered the blissful abode of the Divine Presence, and quaffed the wine of reunion, from the chalice of the beauty of their Lord, the All-Possessing, the Most High." (Bahá’u’lláh, 'Gleanings from the Writings of Bahá’u’lláh’)
*********
God hath, likewise, as a bounty from His presence, abolished the concept of "uncleanness", whereby divers things and peoples have been held to be impure. He, of a certainty, is the Ever-Forgiving, the Most Generous. Verily, all created things were immersed in the sea of purification when, on that first day of Ridvan, We shed upon the whole of creation the splendours of Our most excellent Names and Our most exalted Attributes. This, verily, is a token of My loving providence, which hath encompassed all the worlds. Consort ye then with the followers of all religions, and proclaim ye the Cause of your Lord, the Most Compassionate; this is the very crown of deeds, if ye be of them who understand. (Bahá’u’lláh, ‘The Kitab-i-Aqdas’)
