The principle of collective security He unreservedly urges; recommends the reduction in national armaments; and proclaims as necessary and inevitable the convening of a world gathering at which the kings and rulers of the world will deliberate for the establishment of peace among the nations.

Justice He extols as “the light of men” and their “guardian,” as “the revealer of the secrets of the world of being, and the standard-bearer of love and bounty”; declares its radiance to be incomparable; affirms that upon it must depend “the organization of the world and the tranquillity of mankind.” He characterizes its “two pillars”—“reward and punishment”—as “the sources of life” to the human race; warns the peoples of the world to bestir themselves in anticipation of its advent; and prophesies that, after an interval of great turmoil and grievous injustice, its day-star will shine in its full splendor and glory.

He, furthermore, inculcates the principle of “moderation in all things”; declares that whatsoever, be it “Liberty, civilization and the like,” “passeth beyond the limits of moderation” must “exercise a pernicious influence upon men”; observes that western civilization has gravely perturbed and alarmed the peoples of the world; and predicts that the day is approaching when the “flame” of a civilization “carried to excess” “will devour the cities.”

Consultation He establishes as one of the fundamental principles of His Faith; describes it as “the lamp of guidance,” as “the bestower of understanding,” and as one of the two “luminaries” of the “heaven of Divine wisdom.” Knowledge, He states, is “as wings to man’s life and a ladder for his ascent”; its acquisition He regards as “incumbent upon every one”; considers “arts, crafts and sciences” to be conducive to the exaltation of the world of being; commends the wealth acquired through crafts and professions; acknowledges the indebtedness of the peoples of the world to scientists and craftsmen; and discourages the study of such sciences as are unprofitable to men, and “begin with words and end with words.”

The injunction to “consort with all men in a spirit of friendliness and fellowship” He further emphasizes, and recognizes such association to be conducive to “union and concord,” which, He affirms, are the establishers of order in the world and the quickeners of nations. The necessity of adopting a universal tongue and script He repeatedly stresses; deplores the waste of time involved in the study of divers languages; affirms that with the adoption of such a language and script the whole earth will be considered as “one city and one land”; and claims to be possessed of the knowledge of both, and ready to impart it to any one who might seek it from Him.

To the trustees of the House of Justice He assigns the duty of legislating on matters not expressly provided in His writings, and promises that God will “inspire them with whatsoever He willeth.” The establishment of a constitutional form of government, in which the ideals of republicanism and the majesty of kingship, characterized by Him as “one of the signs of God,” are combined, He recommends as a meritorious achievement; urges that special regard be paid to the interests of agriculture; and makes specific reference to “the swiftly appearing newspapers,” describes them as “the mirror of the world” and as “an amazing and potent phenomenon,” and prescribes to all who are responsible for their production the duty to be sanctified from malice, passion and prejudice, to be just and fair-minded, to be painstaking in their inquiries, and ascertain all the facts in every situation.

The doctrine of the Most Great Infallibility He further elaborates; the obligation laid on His followers to “behave towards the government of the country in which they reside with loyalty, honesty and truthfulness,” He reaffirms; the ban imposed upon the waging of holy war and the destruction of books He reemphasizes; and He singles out for special praise men of learning and wisdom, whom He extols as “eyes” to the body of mankind, and as the “greatest gifts” conferred upon the world.

Nor should a review of the outstanding features of Bahá’u’lláh’s writings during the latter part of His banishment to Akká fail to include a reference to the Lawḥ-i-Hikmat (Tablet of Wisdom), in which He sets forth the fundamentals of true philosophy, or to the Tablet of Visitation revealed in honor of the Imám Ḥusayn, whose praises He celebrates in glowing language; or to the “Questions and Answers” which elucidates the laws and ordinances of the Kitáb-i-Aqdas; or to the “Lawḥ-i-Burhán” (Tablet of the Proof) in which the acts perpetrated by Shaykh Muḥammad-Báqir, surnamed “Dhi’b” (Wolf), and Mír Muḥammad-Ḥusayn, the Imám-Jum’ih of Iṣfáhán, surnamed “Raqshá” (She-Serpent), are severely condemned; or to the Lawḥ-i-Karmil (Tablet of Carmel) in which the Author significantly makes mention of “the City of God that hath descended from heaven,” and prophesies that “erelong will God sail His Ark” upon that mountain, and “will manifest the people of Bahá.” Finally, mention must be made of His Epistle to Shaykh Muḥammad-Taqí, surnamed “Ibn-i-Dhi’b” (Son of the Wolf), the last outstanding Tablet revealed by the pen of Bahá’u’lláh, in which He calls upon that rapacious priest to repent of his acts, quotes some of the most characteristic and celebrated passages of His own writings, and adduces proofs establishing the validity of His Cause.

With this book, revealed about one year prior to His ascension, the prodigious achievement as author of a hundred volumes, repositories of the priceless pearls of His Revelation, may be said to have practically terminated—volumes replete with unnumbered exhortations, revolutionizing principles, world-shaping laws and ordinances, dire warnings and portentous prophecies, with soul-uplifting prayers and meditations, illuminating commentaries and interpretations, impassioned discourses and homilies, all interspersed with either addresses or references to kings, to emperors and to ministers, of both the East and the West, to ecclesiastics of divers denominations, and to leaders in the intellectual, political, literary, mystical, commercial and humanitarian spheres of human activity.

“We, verily,” wrote Bahá’u’lláh, surveying, in the evening of His life, from His Most Great Prison, the entire range of this vast and weighty Revelation, “have not fallen short of Our duty to exhort men, and to deliver that whereunto I was bidden by God, the Almighty, the All-Praised.” “Is there any excuse,” He further has stated, “left for any one in this Revelation? No, by God, the Lord of the Mighty Throne! My signs have encompassed the earth, and my power enveloped all mankind.”
