“The verses which have rained from this Cloud of Divine mercy,” [the Báb’s] is Bahá’u’lláh’s testimony in the Kitáb-i-Íqán, “have been so abundant that none hath yet been able to estimate their number. A score of volumes are now available. How many still remain beyond our reach! How many have been plundered and have fallen into the hands of the enemy, the fate of which none knoweth!” No less arresting is the variety of themes presented by these voluminous writings, such as prayers, homilies, orations, Tablets of visitation, scientific treatises, doctrinal dissertations, exhortations, commentaries on the Qur’án and on various traditions, epistles to the highest religious and ecclesiastical dignitaries of the realm, and laws and ordinances for the consolidation of His Faith and the direction of its activities.
