This chapter examines a text dated 1269/8/25 and attributed to Eison that purports to record a direct esoteric transmission from Mañjuśrī to Eison to Shinkū. This chapter shows, however, that the text’s provenance is more complex than previously acknowledged. I argue that to evaluate the text, we must consider both the influence from hagiographical accounts of the Shingon-Kegon monk Myōe (1173-1232) and an increasing esotericization of the Saidaiji order after Eison’s death in 1290. I further suggest that Eison’s reputed 1269 transmission served to legitimize the transition from Eison to Shinkū and successive Saidaiji elders as well as the very relationship between Shingon and Ritsu in the order. By analyzing these developments alongside the related synthesis of esoteric and exoteric precept traditions in fourteenth-century Myōe-lineage transmission texts, this chapter underscores how dream-visions legitimized varied exoteric-esoteric formulations of medieval Nara monastics, including those of later followers of Eison and Myōe.
