Heian Period Developments in Japanese Esoteric Buddhist Practice: The Case of the Fugen Enmei Ritual and its Various Honzons

Absztrakt

The present paper addresses esoteric Buddhist rituals in Japan, with special focus on the changes that happened in its practice in the first couple of centuries after its initial arrival to the country. Although esotericism originated in India, it was the brief spotlight it gained in China during the Tang Dynasty (especially in the 8th century) that determined its transmission to Japan in the beginning of the 9th century, where it spread rapidly and reached a particular culmination within the same time period, i.e., the Heian Period (794 to 1185/1192). On the one hand, the Shingon school, established by the monk Kūkai (774-835), was essentially the first time the esoteric Buddhist teachings were systematised, and although the founder’s person and teachings are still very much revered to this day, changes have begun right after his death in 835. On the other hand, the Tendai school, a rival for imperial recognition and support and also established (or rather introduced) in the beginning of the 9th century by the monk Saichō (767-822, a contemporary of Kūkai) included some esoteric teachings, and with the practices introduced by later Tendai monks, such as Ennin (794-864) or Enchin (814-891), this school cultivated esoteric practices that are still extant in Japan today.
Firstly, the meaning and usage of the honzon (an icon of a deity) in esoteric Buddhist rituals is clarified in the paper, while later the evolution of two specific icons that were used during the Fugen Enmei rituals of both the Shingon and Tendai schools is introduced, with explanations as to why there are two different types of iconographies extant for the same kind of ritual. The paper contributes to the study of those esoteric practices that were created and developed in a locally recognized Buddhist milieu that served specific purposes in Japan and are found in no other Buddhist cultures in Asia.
