This volume of essays is a very mixed bag with contributions that range from solid, well-documented academic studies and translations produced by professional scholars, on the one hand, to narrow repetition of doctrinaire Baha'i viewpoints by (and presumably for) pious believers, on the other. Several of the academic studies (McCants, Brown, Lawson, Lambden, Quinn, Ghaemmaghami) are particularly notable for examining various works of Sayyid 'Ali Muhammad Shirazi ("the Bab") in the general context of Shirazi's Twelver Shi'i background and his specific connections with the esoteric and messianic thinking of the Shaykhi movement, although some of the translations would have benefited from more extensive notes explaining the often obscure Twelver Shi'i symbolism that Shirazi employed. This book appears most suitable for those who have a serious interest in Shirazi's works and some background knowledge on the Babi movement.
