An early collection of writings and talks of Abdu'l-Baha. Notes on Divine Philosophy compiled by Isabel Fraser Chamberlain

The Epistle to the Son of the Wolf is the last major work of Bahá’u’lláh, founder of the Bahá’í Faith. It was written in 1891 just before his passing in 1892.

The Tablets of Bahá’u’lláh Revealed After the Kitáb-i-Aqdas are selected tablets written by Bahá’u’lláh, the founder of the Bahá’í Faith, and published together as of 1978. As his mission drew to a close after his writing of the Kitáb-i-Aqdas in 1873, he continued to write unnumbered tablets and letters, doing so until the last days of his life in 1892. Six of the tablets in this volume were translated into English and published in 1917. The translations were improved upon by Shoghi Effendi, and those not translated by him were filled in with the publication in 1978 under the supervision of the Universal House of Justice.

A treatise written in reply to a question from Siyyid Yúsuf-i-Sidihí Iṣfahání who had asked the question of how the promised Mahdi could have been ‘transformed’ into the Báb.

Gleanings from the Writings of Bahá'u'lláh is a compilation of selected tablets and extracts from tablets by Bahá'u'lláh, the founder of the Bahá'í Faith. Shoghi Effendi, head of the Bahá'í Faith from 1921 to 1957, made the selection and performed the translation, which was first published 1935. The work consists of a selection of the most characteristic and hitherto unpublished passages from the outstanding works of the Author of the Bahá'í Revelation, according to Shoghi Effendi. The passages come from the whole range of Bahá'u'lláh's writings, dated from about 1853 to 1892.

Selections of prayers and meditations of Bahá’u’lláh compiled and transated by Shoghi Effendi

The Summons of the Lord of Hosts is a collection of the tablets of Bahá’u’lláh that were written to the kings and rulers of the world during his exile in Adrianople and in the early years of his exile to the fortress town of ‘Akká in 1868.

The Tabernacle of Unity is a small book, first published in July 2006, containing Bahá'u'lláh's Tablet, from the early `Akká period, to Mánikchí Sáhib, a prominent Zoroastrian, and a companion Tablet addressed to Mírzá Abu'l-Fadl, the secretary to Mánikchí Sáhib at that time. These, together with three shorter inspirational Tablets, offer a glimpse of Bahá'u'lláh’s relationship with the followers of Zoroastrianism.

Gem-like utterances constituting the supreme ethical work of Bahá’u’lláh

The Kitáb-i-Aqdas or Aqdas is the central book of the Bahá’í Faith written by Bahá’u’lláh, the founder of the religion, 1853-1873. It has the same status as the Quran for Muslims or the Bible for Christians. The work was written in Arabic under the Arabic title, but it is commonly referred to by its Persian title, Kitáb-i-Aqdas, which was given to the work by Bahá’u’lláh himself. It is sometimes also referred to as the Most Holy Book, the Book of Laws or the Book of Aqdas. The word Aqdas has a significance in many languages as the superlative form of a word with its primary letters Q-D-Š. It is usually stated that the book was completed around 1873, although there is evidence to suggest that at least some of the work was written earlier. The Aqdas is referred to as the Mother-Book of the Bahá’í teachings, and the Charter of the future world civilization. It is not, however, only a ‘book of laws’: much of the content deals with other matters, notably ethical exhortations and addresses to various individuals, groups, and places. The Aqdas also discusses the establishment of Bahá’í administrative institutions, Bahá’í religious practices, mysticism, laws of personal status, criminal law, spiritual and ethical exhortations, social principles, miscellaneous laws and abrogations, and prophecies.

Also called by Bahá’u’lláh Siyyid-i-Kutúb, the Lord of Books. This book is the primary doctrinal work of the Bahá’í Faith - in which Bahá’u’lláh sweeps away the age-long barriers that have so insurmountably separated the great religions of the world’...

The Secret of Divine Civilization is a book written in 1875 by `Abdu'l-Bahá, addressed to the rulers and the people of Persia. It is considered to be part of the authoritative religious text of the Bahá'í Faith. The work was lithographed in Bombay in 1882 and received wide circulation in Iran under the Persian title Risali-yi-madaniyyih or the Treatise on Civilization.
