Baha'u'llah The King of Glory - by H. M. Balyuzi

These pages will relate the story of Bahá'u'lláh, as well as the story of the retrogression of a nation under the yoke of the Qájárs.' With these words Mr. Balyuzi introduces this biography of the Founder of the Bahá'í Faith. The life and times of Bahá'u'lláh are presented in their historical setting both in Iran and in the world at large. Much of its story is taken from the unpublished memoirs of His companions who themselves observed the events they describe. Details are given of Bahá'u'lláh's ancestry and family, His several journeys when banished from Iran, with the names of those who accompanied Him to Constantinople and into the citadel of 'Akká; the horrific martyrdom of Badí, His messenger to the Shah; the background of the marriage of 'Abdu'l-Bahá, His eldest son; the machinations of the Azalís in Constantinople which brought Him anxiety and sorrow in His last years; and the closing months of His life at Bahjí.

Epistle to the Son of the Wolf -- by Baha'u'llah

This is the last major Tablet of Baha’u’llah – the last of the hundred books He revealed. It was written to a priest in Isfahan, Persia, called the “Son of the Wolf”, whose father had sent the two martyrs known as the “King of Martyrs” and the “Beloved of Martyrs” to their deaths. This priest had committed the unforgivable sin: he had violated the Covenant and blasphemed against the Holy Spirit; that is, he had hated, not the lamp, or the Prophet of God as an individual – either from ignorance or because he did not recognize Him – but the Light of God itself which the Prophet reflects. He had hated the Light in the lamp, and “this destruction of the Light, ”’Abdu’l-Baha says in Some Answered Questions,” has no remedy.”
