"In this day the choicest fruit of the tree of knowledge is that which serveth the welfare of humanity and safeguardeth its interests."

"Say: O ye that have eyes to see! The past is the mirror of the future. Gaze ye therein and be apprised thereof; perchance ye may be aided thereby to recognize the Friend and may be not the cause of His displeasure.
In this day the choicest fruit of the tree of knowledge is that which serveth the welfare of humanity and safeguardeth its interests."

-Bahá'u'lláh, The Tabernacle of Unity , p. 10

"Whoso hath been reborn in this Day, shall never die; whoso remaineth dead, shall never live."

"We can well perceive how the whole human race is encompassed with great, with incalculable afflictions. We see it languishing on its bed of sickness, sore-tried and disillusioned. They that are intoxicated by self-conceit have interposed themselves between it and the Divine and infallible Physician. Witness how they have entangled all men, themselves included, in the mesh of their devices. They can neither discover the cause of the disease, nor have they any knowledge of the remedy. They have conceived the straight to be crooked, and have imagined their friend an enemy.

Incline your ears to the sweet melody of this Prisoner. Arise, and lift up your voices, that haply they that are fast asleep may be awakened. Say: O ye who are as dead! The Hand of Divine bounty proffereth unto you the Water of Life. Hasten and drink your fill. Whoso hath been reborn in this Day, shall never die; whoso remaineth dead, shall never live."

-Bahá'u'lláh, The Tabernacle of Unity, p. 5-6

"The Lord of celestial wisdom saith: A harsh word is even as a sword thrust; a gentle word as milk."

"O people! Words must be supported by deeds, for deeds are the true test of words. Without the former, the latter can never quench the thirst of the yearning soul, nor unlock the portals of vision before the eyes of the blind. The Lord of celestial wisdom saith: A harsh word is even as a sword thrust; a gentle word as milk. The latter leadeth the children of men unto knowledge and conferreth upon them true distinction."

-Bahá'u'lláh, The Tabernacle of Unity, pp. 8-9

"Say: O people! Walk ye neath the shadow of justice and truthfulness and seek ye shelter within the tabernacle of unity."

"The incomparable Friend saith: The path to freedom hath been outstretched; hasten ye thereunto. The wellspring of wisdom is overflowing; quaff ye therefrom. Say: O well-beloved ones! The tabernacle of unity hath been raised; regard ye not one another as strangers. Ye are the fruits of one tree, and the leaves of one branch. Verily I say, whatsoever leadeth to the decline of ignorance and the increase of knowledge hath been, and will ever remain, approved in the sight of the Lord of creation. Say: O people! Walk ye neath the shadow of justice and truthfulness and seek ye shelter within the tabernacle of unity."

-Bahá'u'lláh, The Tabernacle of Unity, p. 9

"O people! The darkness of greed and envy becloudeth the radiance of the soul ..."

"O children of understanding! If the eyelid, however delicate, can deprive man’s outer eye from beholding the world and all that is therein, consider then what would be wrought if the veil of covetousness were to descend upon his inner eye. Say: O people! The darkness of greed and envy becloudeth the radiance of the soul even as the clouds obstruct the light of the sun. Should anyone hearken unto this utterance with a discerning ear, he will unfurl the wings of detachment and soar effortlessly in the atmosphere of true understanding."

-Bahá'u'lláh, The Tabernacle of Unity, pp. 7-8

"This is the day whereon every man may accede unto everlasting honour ..."

"In this day He Who is the Lord, the Ruler, the Fashioner, and the Refuge of the world hath appeared. Let every ear be eager to hearken unto that which will be revealed from the kingdom of His will; let every eye be expectant to gaze upon that which will shine forth from the Daystar of knowledge and wisdom. By Him Who is the Desire of the world! This is the day for eyes to see and for ears to hear, for hearts to perceive and for tongues to speak forth. Blessed are they that have attained thereunto; blessed are they that have sought after and recognized it! This is the day whereon every man may accede unto everlasting honour, for whatsoever hath streamed forth from the Pen of Glory in regard to any soul is adorned with the ornament of immortality. Again, blessed are they that have attained thereunto!"

-Bahá'u'lláh, The Tabernacle of Unity, p. 52

" ... these holy Souls are one: the first among them is the same as the last, and the last is the same as the first."

"Regarding their statement that “our faith and religion is superior to every other”, by this is meant such Prophets as have appeared before them. Viewed from one perspective these holy Souls are one: the first among them is the same as the last, and the last is the same as the first. All have proceeded from God, unto Him have they summoned all men, and unto Him have they returned. This theme hath been set forth in the Book of Certitude, which is indeed the cynosure of all books, and which streamed from the Pen of Glory in the early years of this Most Great Revelation. Blessed is he that hath beheld it and pondered its contents for the love of God, the Lord of creation."

-Bahá'u'lláh, The Tabernacle of Unity, p. 45
