Zoroaster lived about a thousand years before Christ. There is no exact date in the teachings regarding the beginning of His Dispensation. The personages in Zenda-Avesta cannot be absolutely relied upon, as the Avesta is not to be regarded as the authentic compilation of the writings of the Prophet. (From a letter written on behalf of Shoghi Effendi to National Committee and an individual believer, dated 30 July 1941; The Compilation of Compilations, vol. I, Extracts from the Baha’i Writings on Buddha, Krishna, Zoroaster, and related subjects)
