You may have missed Dr. Sohrab Kourosh’s Web Talk on the Kitáb-i-Iqán, but you can access it anytime in the Wilmette Institute’s library of Web Talks and also print out his PowerPoint to enhance your study. About his course, Dr. Kourosh wrote this:
The Kitáb-i-Íqán (The Book of Certitude), which was designated by Bahá’u’lláh as the Lord of Books revealed by the Most Exalted Pen and called by ‘Abdu’l-Bahá the fountainhead of the water of eternal life, is unique in the history of religions and holy scriptures. This book is not only the key for opening the mysteries of the past holy scriptures, but it revolutionizes the concepts of religion, eschatology, and theology by resolving and removing eschatological barriers and establishing the fundamentals of a universal religion and a universal theology that integrates and harmonizes the contending religious ideologies.
In his talk, Dr. Kourosh covers these topics: what the Kitáb-i-Iqán is and its scriptural significance; place in Bahá’í literature; style; historical background; publication and translation; major themes; new concepts of religion, eschatology (the time of the end), theology, and more; and essential objective. He concludes his talk with a quotation from the writings of Shoghi Effendi: “The Íqán is the most important book written on the spiritual significance of the Cause. I do not believe any person can consider himself well versed in the teachings unless he has studied it thoroughly.”
