 He also authored several manuscripts that remain unpublished, including "Unveiling of the Truths" ("Kashf al-Haqa'iq"), which describes the genesis of the universe and the role of human beings.In 1963 Elahi published his first book, ""Demonstration of the Truth" (Burhān al-Ḥaqq)," a theological work which presented for the first time an authoritative historical account of the Ahl-e Haqq, including its development, fundamental principles, and sacred rites, which until then had been kept secret.The book also addressed the esoteric aims shared in common by the Qur'an, Islam, and the Ahl-e Haqq.
