Bahá'u'lláh (ba-haa-ol-laa بهاءالله Arabic for "Glory of God") (12 November 1817 – 29 May 1892), born Mírzá Husayn-`Alí (Persian:میرزا حسین علی), was the founder of the Bahá'í Faith, and father of `Abdu'l-Bahá. Bahá'u'lláh authored many religious works, most notably the Kitáb-i-Aqdas and the Book of Certitude.
- Every age hath its own problem, and every soul its particular aspiration. The remedy the world needeth in its present-day afflictions can never be the same as that which a subsequent age may require. Be anxiously concerned with the needs of the age ye live in, and centre your deliberations on its exigencies and requirements.
- It behoveth the sovereigns of the world may God assist them or the ministers of the earth to take counsel together and to adopt one of the existing languages or a new one to be taught to children in schools throughout the world, and likewise one script. Thus the whole earth will come to be regarded as one country.
- O YE PEOPLE THAT HAVE MINDS TO KNOW AND EARS TO HEAR!
The first call of the Beloved is this: O mystic nightingale! Abide not but in the rose-garden of the spirit. O messenger of the Solomon of love! Seek thou no shelter except in the Sheba of the well-beloved, and O immortal phoenix! dwell not save on the mount of faithfulness. Therein is thy habitation, if on the wings of thy soul thou soarest to the realm of the infinite and seekest to attain thy goal.
- It is incumbent upon everyone to aid those daysprings of authority and sources of command who are adorned with the ornamant of equity and justice.
- Kitáb-i-`Ahd (Book of the Covenant)
- If the learned and worldly-wise men of this age were to allow mankind to inhale the fragrance of fellowship and love, every understanding heart would apprehend the meaning of true liberty, and discover the secret of undisturbed peace and absolute composure.
- Lawh-i-Maqsúd (Tablet of Maqsúd)
Epistle to the Son of the Wolf 
- The Divine Messengers have been sent down, and their Books were revealed, for the purpose of promoting the knowledge of God, and of furthering unity and fellowship amongst men. But now behold, how they have made the Law of God a cause and pretext for perversity and hatred. How pitiful, how regrettable, that most men are cleaving fast to, and have busied themselves with, the things they possess, and are unaware of, and shut out as by a veil from, the things God possesseth!
- Justice and equity are twin Guardians that watch over men. From them are revealed such blessed and perspicuous words as are the cause of the well-being of the world and the protection of the nations.
Gleanings from the Writings of Bahá'u'lláh 
- God's purpose in sending His Prophets unto men is twofold. The first is to liberate the children of men from the darkness of ignorance, and guide them to the light of true understanding. The second is to ensure the peace and tranquillity of mankind, and provide all the means by which they can be established.
- The purpose underlying the revelation of every heavenly Book, nay, of every divinely-revealed verse, is to endue all men with righteousness and understanding, so that peace and tranquillity may be firmly established amongst them. Whatsoever instilleth assurance into the hearts of men, whatsoever exalteth their station or promoteth their contentment, is acceptable in the sight of God.
- The time must come when the imperative necessity for the holding of a vast, an all-embracing assemblage of men will be universally realized. The rulers and kings of the earth must needs attend it, and, participating in its deliberations, must consider such ways and means as will lay the foundations of the world's Great Peace amongst men. Such a peace demandeth that the Great Powers should resolve, for the sake of the tranquillity of the peoples of the earth, to be fully reconciled among themselves. Should any king take up arms against another, all should unitedly arise and prevent him. If this be done, the nations of the world will no longer require any armaments, except for the purpose of preserving the security of their realms and of maintaining internal order within their territories.
- It is not for him to pride himself who loveth his own country, but rather for him who loveth the whole world. The earth is but one country and mankind its citizens.
- Man is the supreme Talisman. Lack of a proper education hath, however, deprived him of that which he doth inherently possess. Through a word proceeding out of the mouth of God he was called into being; by one word more he was guided to recognize the Source of his education; by yet another word his station and destiny were safeguarded. The Great Being saith: Regard man as a mine rich in gems of inestimable value. Education can, alone, cause it to reveal its treasures, and enable mankind to benefit therefrom.
The Seven Valleys 
- This station is the dying from self and the living in God, the being poor in self and rich in the Desired One. Poverty as here referred to signifieth being poor in the things of the created world, rich in the things of God’s world. For when the true lover and devoted friend reacheth to the presence of the Beloved, the sparkling beauty of the Loved One and the fire of the lover’s heart will kindle a blaze and burn away all veils and wrappings. Yea, all he hath, from heart to skin, will be set aflame, so that nothing will remain save the Friend
- He who hath attained this station is sanctified from all that pertaineth to the world. Wherefore, if those who have come to the sea of His presence are found to possess none of the limited things of this perishable world, whether it be outer wealth or personal opinions, it mattereth not. For whatever the creatures have is limited by their own limits, and whatever the True One hath is sanctified therefrom; this utterance must be deeply pondered that its purport may be clear. “Verily the righteous shall drink of a winecup tempered at the camphor fountain.” If the interpretation of “camphor” become known, the true intention will be evident. This state is that poverty of which it is said, “Poverty is My glory.” And of inward and outward poverty there is many a stage and many a meaning which I have not thought pertinent to mention here; hence I have reserved these for another time, dependent on what God may desire and fate may seal.
- This is the plane whereon the vestiges of all things (Kullu Shay’)
- O Brother! Not every sea hath pearls; not every branch will flower, nor will the nightingale sing thereon. Then, ere the nightingale of the mystic paradise repair to the garden of God, and the rays of the heavenly morning return to the Sun of Truth—make thou an effort, that haply in this dustheap of the mortal world thou mayest catch a fragrance from the everlasting garden, and live forever in the shadow of the peoples of this city. And when thou hast attained this highest station and come to this mightiest plane, then shalt thou gaze on the Beloved, and forget all else.
- In this Valley, the wayfarer leaveth behind him the stages of the “oneness of Being and Manifestation” and reacheth a oneness that is sanctified above these two stations. Ecstasy alone can encompass this theme, not utterance nor argument; and whosoever hath dwelt at this stage of the journey, or caught a breath from this garden land, knoweth whereof We speak.
- These journeys have no visible ending in the world of time, but the severed wayfarer—if invisible confirmation descend upon him and the Guardian of the Cause assist him—may cross these seven stages in seven steps, nay rather in seven breaths, nay rather in a single breath, if God will and desire it. And this is of “His grace on such of His servants as He pleaseth.”
- They who soar in the heaven of singleness and reach to the sea of the Absolute, reckon this city—which is the station of life in God—as the furthermost state of mystic knowers, and the farthest homeland of the lovers. But to this evanescent One of the mystic ocean, this station is the first gate of the heart’s citadel, that is, man’s first entrance to the city of the heart; and the heart is endowed with four stages, which would be recounted should a kindred soul be found
Quotes about Bahá'u'lláh 
- We spend our lives trying to unlock the mystery of the universe, but there was a Turkish prisoner, Bahá'u'lláh, in Akka, Palestine who had the Key.
