‘”HE” hath now appeared in the raiment of “I”. He Who was hidden from mortal eyes exclaimeth: Lo! I am the All-Manifest.’ "

"In the past the divines were perplexed over this question, a question which He Who is the Sovereign Truth hath, during the early years of His life, Himself heard them ask repeatedly: ‘What is that Word which the Qá’im will pronounce whereby the leaders of religion are put to flight?’ Say, that Word is now made manifest and ye have fled ere ye heard it uttered, although ye perceive it not. And that blessed, that hidden, that concealed and treasured Word is this: ‘”HE” hath now appeared in the raiment of “I”. He Who was hidden from mortal eyes exclaimeth: Lo! I am the All-Manifest.’ This is the Word which hath caused the limbs of disbelievers to quake. Glorified be God! All the heavenly Scriptures of the past attest to the greatness of this Day, the greatness of this Manifestation, the greatness of His signs, the greatness of His Word, the greatness of His constancy, the greatness of His pre-eminent station. Yet despite all this the people have remained heedless and are shut out as by a veil. Indeed all the Prophets have yearned to attain this Day. David saith: ‘Who will bring me into the Strong City?’ 1 By Strong City is meant ‘Akká. Its fortifications are very strong and this Wronged One is imprisoned within its walls. Likewise it is revealed in the Qur’án: ‘Bring forth thy people from the darkness into the light and announce to them the days of God.’ 2"
