Assist ye, O My people, My chosen servants who have arisen to make mention of Me among My creatures and to exalt My Word throughout My realm. These, truly, are the stars of the heaven of My loving providence and the lamps of My guidance unto all mankind. But he whose words conflict with that which hath been sent down in My Holy Tablets is not of Me. Beware lest ye follow any impious pretender. These Tablets are embellished with the seal of Him Who causeth the dawn to appear, Who lifteth up His voice between the heavens and the earth. Lay hold on this Sure Handle and on the Cord of My mighty and unassailable Cause.

Say: God hath made My hidden love the key to the Treasure
There is a well-known Islamic tradition concerning God and His creation:

I was a Hidden Treasure. I wished to be made known, and thus I called creation into being in order that I might be known.

References and allusions to this tradition are found throughout the Bahá’í­ Writings. For example, in one of His prayers, Bahá’u’lláh reveals:

Lauded be Thy name, O Lord my God! I testify that Thou wast a hidden Treasure wrapped within Thine immemorial Being and an impenetrable Mystery enshrined in Thine own Essence. Wishing to reveal Thyself, Thou didst call into being the Greater and the Lesser Worlds, and didst choose Man above all Thy creatures, and didst make Him a sign of both of these worlds, O Thou Who art our Lord, the Most Compassionate!
Thou didst raise Him up to occupy Thy throne before all the people of Thy creation. Thou didst enable Him to unravel Thy mysteries, and to shine with the lights of Thine inspiration and Thy Revelation, and to manifest Thy names and Thine attributes. Through Him Thou didst adorn the preamble of the book of Thy creation, O Thou Who art the Ruler of the universe Thou hast fashioned! (Prayers and Meditations by Bahá’u’lláh, XXXVIII)

Likewise, in the Hidden Words, He states:

O Son of Man! I loved thy creation, hence I created thee. Wherefore, do thou love Me, that I may name thy name and fill thy soul with the spirit of life.

‘Abdu’l-Bahá, in His commentary on the above-cited tradition, wrote:

O wayfarer in the path of the Beloved! Know thou that the main purpose of this holy tradition is to make mention of the stages of God’s concealment and manifestation within the Embodiments of Truth, They who are the Dawning-places of His All-Glorious Being. For example, before the flame of the undying Fire is lit and manifest, it existeth by itself within itself in the hidden identity of the universal Manifestations, and this is the stage of the "Hidden Treasure". And when the blessed Tree is kindled by itself within itself, and that Divine Fire burneth by its essence within its essence, this is the stage of "I wished to be made known". And when it shineth forth from the Horizon of the universe with infinite Divine Names and Attributes upon the contingent and placeless worlds, this constituteth the emergence of a new and wondrous creation which correspondeth to the stage of "Thus I called creation into being". And when the sanctified souls rend asunder the veils of all earthly attachments and worldly conditions, and hasten to the stage of gazing on the beauty of the Divine Presence and are honoured by recognizing the Manifestation and are able to witness the splendour of God’s Most Great Sign in their hearts, then will the purpose of creation, which is the knowledge of Him Who is the Eternal Truth, become manifest.

backbiting or calumny
Backbiting, slander and dwelling on the faults of others have been repeatedly condemned by Bahá’u’lláh. In the Hidden Words, He clearly states: “O Son of Being! How couldst thou forget thine own faults and busy thyself with the faults of others? Whoso doeth this is accursed of Me.” And again: “O Son of Man! Breathe not the sins of others so long as thou art thyself a sinner. Shouldst thou transgress this command, accursed wouldst thou be, and to this I bear witness.” This strong admonition is further reiterated in His last work, “the Book of My Covenant”: “Verily I say, the tongue is for mentioning what is good, defile it not with unseemly talk. God hath forgiven what is past. Henceforward everyone should utter that which is meet and seemly, and should refrain from slander, abuse and whatever causeth sadness in men.”

The Lord hath ordained that those of you who are able shall make pilgrimage to the sacred House
Two sacred Houses are covered by this ordinance, the House of the Báb in Shí­ráz and the House of Bahá’u’lláh in Baghdád. Bahá’u’lláh has specified that pilgrimage to either of these two Houses fulfils the requirement of this passage (Q&A 25, 29). In two separate Tablets, known as Súriy-i-Hajj (Q&A 10), Bahá’u’lláh has prescribed specific rites for each of these pilgrimages. In this sense, the performance of a pilgrimage is more than simply visiting these two Houses.
After the passing of Bahá’u’lláh, ‘Abdu’l-Bahá designated the Shrine of Bahá’u’lláh at Bahjí­ as a place of pilgrimage. In a Tablet, He indicates that the “Most Holy Shrine, the Blessed House in Baghdád and the venerated House of the Báb in Shí­ráz” are “consecrated to pilgrimage”, and that it is “obligatory” to visit these places “if one can afford it and is able to do so, and if no obstacle stands in one’s way”. No rites have been prescribed for pilgrimage to the Most Holy Shrine.

To none is it permitted to seek absolution from another soul
Bahá’u’lláh prohibits confession to, and seeking absolution of one’s sins from, a human being. Instead one should beg forgiveness from God. In the Tablet of Bishárát, He states that “such confession before people results in one’s humiliation and abasement”, and He affirms that God “wisheth not the humiliation of His servants”.
Shoghi Effendi sets the prohibition into context. His secretary has written on his behalf that we

. . . are forbidden to confess to any person, as do the Catholics to their priests, our sins and shortcomings, or to do so in public, as some religious sects do. However, if we spontaneously desire to acknowledge we have been wrong in something, or that we have some fault of character, and ask another person’s forgiveness or pardon, we are quite free to do so.

The Universal House of Justice has also clarified that Bahá’u’lláh’s prohibition concerning the confession of sins does not prevent an individual from admitting transgressions in the course of consultations held under the aegis of Bahá’í­ institutions. Likewise, it does not preclude the possibility of seeking advice from a close friend or of a professional counsellor regarding such matters.

How many a man hath secluded himself in the climes of India, denied himself the things that God hath decreed as lawful, imposed upon himself austerities and mortifications
These verses constitute the prohibition of monasticism and asceticism. See the Synopsis and Codification, section IV.D.1.y.iii.-iv. In the Words of Paradise Bahá’u’lláh amplifies these provisions. He states: “Living in seclusion or practising asceticism is not acceptable in the presence of God,” and He calls upon those involved to “observe that which will cause joy and radiance”. He instructs those who have taken up “their abodes in the caves of the mountains” or who have “repaired to graveyards at night” to abandon these practices, and He enjoins them not to deprive themselves of the “bounties” of this world which have been created by God for humankind. And in the Tablet of Bishárát, while acknowledging the “pious deeds” of monks and priests, Bahá’u’lláh calls upon them to “give up the life of seclusion and direct their steps towards the open world and busy themselves with that which will profit themselves and others”. He also grants them leave “to enter into wedlock that they may bring forth one who will make mention of God”.

Aghsán
"Aghsán" (plural of Ghusn) is the Arabic word for "Branches". This term is used by Bahá’u’lláh to designate His male descendants. It has particular implications not only for the disposition of endowments but also for the succession of authority following the passing of Bahá’u’lláh (see note 145) and of ‘Abdu’l-Bahá. Bahá’u’lláh, in the Book of His Covenant, appointed ‘Abdu’l-Bahá, His eldest son, as the Centre of His Covenant and the Head of the Faith. ‘Abdu’l-Bahá, in His Will and Testament, appointed Shoghi Effendi, His eldest grandson, as the Guardian and Head of the Faith.
This passage of the Aqdas, therefore, anticipates the succession of chosen Aghsán and thus the institution of the Guardianship and envisages the possibility of a break in their line. The passing of Shoghi Effendi in 1957 precipitated the very situation provided for in this passage, in that the line of Aghsán ended before the Universal House of Justice had been established (see note 67).

Shave not your heads
In some religious traditions it is considered desirable to shave one’s head. The shaving of the head is forbidden by Bahá’u’lláh, and He makes it clear that the provision contained in His Súriy-i-Hajj requiring pilgrims to the Holy House in Shí­ráz to shave their heads has been superseded through this verse of the Kitáb-i-Aqdas (Q&A 10).

He Who is the Dawning-place of God’s Cause hath no partner in the Most Great Infallibility.
In the Tablet of Ishráqát, Bahá’u’lláh affirms that the Most Great Infallibility is confined to the Manifestations of God.
Chapter 45 in Some Answered Questions is devoted to an explanation by ‘Abdu’l-Bahá of this verse of the Aqdas. In this chapter He stresses, among other things, the inseparability of essential “infallibility” from the Manifestations of God, and asserts that “whatever emanates from Them is identical with the truth, and conformable to reality”, that “They are not under the shadow of the former laws”, and “Whatever They say is the word of God, and whatever They perform is an upright action”.

the destruction of books
In the Tablet of Ishráqát Bahá’u’lláh, referring to the fact that the Báb had made the laws of the Bayán subject to His sanction, states that He put some of the Báb’s laws into effect “by embodying them in the Kitáb-i-Aqdas in different words”, while others He set aside.
With regard to the destruction of books, the Bayán commanded the Báb’s followers to destroy all books except those that were written in vindication of the Cause and Religion of God. Bahá’u’lláh abrogates this specific law of the Bayán.
As to the nature and severity of the laws of the Bayán, Shoghi Effendi in a letter written on his behalf provides the following comment:

The severe laws and injunctions revealed by the Báb can be properly appreciated and understood only when interpreted in the light of His own statements regarding the nature, purpose and character of His own Dispensation. As these statements clearly reveal, the Bábí­ Dispensation was essentially in the nature of a religious and indeed social revolution, and its duration had therefore to be short, but full of tragic events, of sweeping and drastic reforms. Those drastic measures enforced by the Báb and His followers were taken with the view of undermining the very foundations of Shí­'ih orthodoxy, and thus paving the way for the coming of Bahá’u’lláh. To assert the independence of the new Dispensation, and to prepare also the ground for the approaching Revelation of Bahá’u’lláh, the Báb had therefore to reveal very severe laws, even though most of them were never enforced. But the mere fact that He revealed them was in itself a proof of the independent character of His Dispensation and was sufficient to create such widespread agitation, and excite such opposition on the part of the clergy that led them to cause His eventual martyrdom.

the one whose power transcended thy power, and whose station excelled thy station
This is a reference to Napoleon III (1808-1873), the Emperor of the French, who was regarded by many historians as the most outstanding monarch of his day in the West.
Bahá’u’lláh addressed two Tablets to Napoleon III, in the second of which He clearly prophesied that Napoleon’s kingdom would be “thrown into confusion”, that his “empire shall pass” from his hands, and that his people would experience great “commotions”.
Within a year, Napoleon III suffered a resounding defeat, at the hands of Kaiser William I, at the Battle of Sedan in 1870. He went in exile to England, where he died three years later.

These Tablets are embellished with the seal of Him Who causeth the dawn to appear, Who lifteth up His voice between the heavens and the earth.
Bahá’u’lláh repeatedly affirms the absolute integrity of His Writings as the Word of God. Some of His Tablets also bear the mark of one of His seals. The Bahá’í­ World, volume V, p. 4, contains a photograph of a number of Bahá’u’lláh’s seals.

turn your faces toward Him Whom God hath purposed, Who hath branched from this Ancient Root
Bahá’u’lláh here alludes to ‘Abdu’l-Bahá as His Successor and calls upon the believers to turn towards Him. In the Book of the Covenant, His Will and Testament, Bahá’u’lláh discloses the intention of this verse. He states: “The object of this sacred verse is none other except the Most Mighty Branch.” The “Most Mighty Branch” is one of the titles conferred by Bahá’u’lláh on ‘Abdu’l-Bahá. (See also notes 66 and 184.)

It hath been forbidden you to carry arms unless essential
Bahá’u’lláh confirms an injunction contained in the Bayán which makes it unlawful to carry arms, unless it is necessary to do so. With regard to circumstances under which the bearing of arms might be “essential” for an individual, ‘Abdu’l-Bahá gives permission to a believer for self-protection in a dangerous environment. Shoghi Effendi in a letter written on his behalf has also indicated that, in an emergency, when there is no legal force at hand to appeal to, a Bahá’í­ is justified in defending his life. There are a number of other situations in which weapons are needed and can be legitimately used; for instance, in countries where people hunt for their food and clothing, and in such sports as archery, marksmanship, and fencing.
On the societal level, the principle of collective security enunciated by Bahá’u’lláh (see Gleanings from the Writings of Bahá’u’lláh, CXVII) and elaborated by Shoghi Effendi (see the Guardian’s letters in The World Order of Bahá’u’lláh) does not presuppose the abolition of the use of force, but prescribes "a system in which Force is made the servant of Justice", and which provides for the existence of an international peace-keeping force that "will safeguard the organic unity of the whole commonwealth". In the Tablet of Bishárát, Bahá’u’lláh expresses the hope that “weapons of war throughout the world may be converted into instruments of reconstruction and that strife and conflict may be removed from the midst of men”.
In another Tablet Bahá’u’lláh stresses the importance of fellowship with the followers of all religions; He also states that “the law of holy war hath been blotted out from the Book”.

Take heed lest the word
Bahá’u’lláh cautions people “of insight” not to allow their interpretations of the Holy Scriptures to prevent them from recognizing the Manifestation of God. Followers of each religion have tended to allow their devotion to its Founder to cause them to perceive His Revelation as the final Word of God and to deny the possibility of the appearance of any subsequent Prophet. This has been the case of Judaism, Christianity and Islám. Bahá’u’lláh denies the validity of this concept of finality both in relation to past Dispensations and to His own. With regard to Muslims, He wrote in the Kitáb-i-íqán that the “people of the Qur’án . . . have allowed the words ’seal of the Prophets' to veil their eyes”, “to obscure their understanding, and deprive them of the grace of all His manifold bounties”. He affirms that “this theme hath . . . been a sore test unto all mankind”, and laments the fate of “those who, clinging unto these words, have disbelieved in Him Who is their true Revealer”. The Báb refers to this same theme when He warns: “Let not names shut you out as by a veil from Him Who is their Lord, even the name Prophet, for such a name is but a creation of His utterance.”

Call ye to mind Karí­m
Hájí­ Mí­rzá Muhammad Karí­m Khán-i-Kirmání­ (1810-circa 1873) was the self-appointed leader of the Shaykhí­ community after the death of Siyyid Kázim, who was the appointed successor to Shaykh Ahmad-i-Ahsá’í­ (see notes 171 and 172). He dedicated himself to the promotion of the teachings of Shaykh Ahmad. The opinions he expressed became the subject of controversy among his supporters and opponents alike.
Regarded as one of the leading savants and prolific authors of his age, he composed numerous books and epistles in the various fields of learning that were cultivated in those times. He actively opposed both the Báb and Bahá’u’lláh, and used his treatises to attack the Báb and His Teachings. In the Kitáb-i-íqán, Bahá’u’lláh condemns the tone and content of his writings and singles out for criticism one of his works which contains negative allusions to the Báb. Shoghi Effendi describes him as "inordinately ambitious and hypocritical" and describes how he "at the special request of the Sháh had in a treatise viciously attacked the new Faith and its doctrines".

O ye the learned ones in Bahá
Bahá’u’lláh eulogizes the learned among His followers. In the Book of His Covenant, He wrote: “Blessed are the rulers and learned among the people of Bahá.” Referring to this statement, Shoghi Effendi has written:

In this holy cycle the “learned” are, on the one hand, the Hands of the Cause of God, and, on the other, the teachers and diffusers of His Teachings who do not rank as Hands, but who have attained an eminent position in the teaching work. As to the "rulers" they refer to the members of the Local, National and International Houses of Justice. The duties of each of these souls will be determined in the future.

The Hands of the Cause of God were individuals appointed by Bahá’u’lláh and charged with various duties, especially those of protecting and propagating His Faith. In Memorials of the Faithful ‘Abdu’l-Bahá referred to other outstanding believers as Hands of the Cause, and in His Will and Testament He included a provision calling upon the Guardian of the Faith to appoint Hands of the Cause at his discretion. Shoghi Effendi first raised posthumously a number of the believers to the rank of Hands of the Cause, and during the latter years of his life appointed a total of 32 believers from all continents to this position. In the period between the passing of Shoghi Effendi in 1957 and the election of the Universal House of Justice in 1963, the Hands of the Cause directed the affairs of the Faith in their capacity as Chief Stewards of Bahá’u’lláh’s embryonic World Commonwealth (see note 67). In November 1964, the Universal House of Justice determined that it could not legislate to make it possible to appoint Hands of the Cause. Instead, by a decision of the House of Justice in 1968, the functions of the Hands of the Cause in relation to protecting and propagating the Faith were extended into the future by the creation of the Continental Boards of Counsellors, and in 1973 through the establishment of the International Teaching Centre, which has its seat in the Holy Land.
The Universal House of Justice appoints the Counsellor members of the International Teaching Centre and the Continental Counsellors. Members of Auxiliary Boards are appointed by the Continental Counsellors. All these individuals fall within the definition of the “learned” given by Shoghi Effendi in the statement quoted above.

this new World Order
In the Persian Bayán, the Báb stated: “Well is it with him who fixeth his gaze upon the Order of Bahá’u’lláh, and rendereth thanks unto his Lord. For He will assuredly be made manifest. God hath indeed irrevocably ordained it in the Bayán.” Shoghi Effendi identifies this “Order” with the System Bahá’u’lláh envisages in the Aqdas, in which He testifies to its revolutionizing effect on the life of humanity and reveals the laws and principles which govern its operation.
The features of the “new World Order” are delineated in the Writings of Bahá’u’lláh and ‘Abdu’l-Bahá and in the letters of Shoghi Effendi and the Universal House of Justice. The institutions of the present-day Bahá’í­ Administrative Order, which constitute the "structural basis" of Bahá’u’lláh’s World Order, will mature and evolve into the Bahá’í­ World Commonwealth. In this regard, Shoghi Effendi affirms that the Administrative Order "will, as its component parts, its organic institutions, begin to function with efficiency and vigour, assert its claim and demonstrate its capacity to be regarded not only as the nucleus but the very pattern of the New World Order destined to embrace in the fullness of time the whole of mankind".
For additional information on the evolution of this new World Order, see, for example, the letters of Shoghi Effendi published in The World Order of Bahá’u’lláh.

Select ye a single language . . . adopt ye . . . a common script.
Bahá’u’lláh enjoins the adoption of a universal language and script. His Writings envisage two stages in this process. The first stage is to consist of the selection of an existing language or an invented one which would then be taught in all the schools of the world as an auxiliary to the mother tongues. The governments of the world through their parliaments are called upon to effect this momentous enactment. The second stage, in the distant future, would be the eventual adoption of one single language and common script for all on earth.

We have appointed two signs for the coming of age of the human race
The first sign of the coming of age of humanity referred to in the Writings of Bahá’u’lláh is the emergence of a science which is described as that “divine philosophy” which will include the discovery of a radical approach to the transmutation of elements. This is an indication of the splendours of the future stupendous expansion of knowledge.
Concerning the “second” sign which Bahá’u’lláh indicates to have been revealed in the Kitáb-i-Aqdas, Shoghi Effendi states that Bahá’u’lláh, ". . . in His Most Holy Book, has enjoined the selection of a single language and the adoption of a common script for all on earth to use, an injunction which, when carried out, would, as He Himself affirms in that Book, be one of the signs of the 'coming of age of the human race'".
Further insight into this process of mankind’s coming of age and proceeding to maturity is provided by the following statement of Bahá’u’lláh:

One of the signs of the maturity of the world is that no one will accept to bear the weight of kingship. Kingship will remain with none willing to bear alone its weight. That day will be the day whereon wisdom will be manifested among mankind.

The coming of age of the human race has been associated by Shoghi Effendi with the unification of the whole of mankind, the establishment of a world commonwealth, and an unprecedented stimulus to "the intellectual, the moral and spiritual life of the entire human race".

Question: Shaving the head hath been forbidden in the Kitáb-i-Aqdas but enjoined in the Súriy-i-Hajj.
Answer: All are charged with obedience to the Kitáb-i-Aqdas; whatsoever is revealed therein is the Law of God amid His servants. The injunction on pilgrims to the sacred House to shave the head hath been lifted.

Question: Concerning disparities between certain revealed verses.
Answer: Many Tablets were revealed and dispatched in their original form without being checked and reviewed. Consequently, as bidden, they were again read out in the Holy Presence, and brought into conformity with the grammatical conventions of the people in order to forestall the cavils of opponents of the Cause. Another reason for this practice is that the new style inaugurated by the Herald, may the souls of all else but Him be offered up for His sake, was seen to be marked by substantial latitude in adherence to the rules of grammar; sacred verses therefore were then revealed in a style which is for the most part in conformity with current usage for ease of understanding and concision of expression.

In the Tablet to Abá Badí­', this holy verse hath been revealed: "Verily, We have enjoined on every son to serve his father." Such is the decree which We have set forth in the Book.
