This dissertation is a study of the life of the Kukai (774-822), known posthumously by the honorific title Kobo Daishi (Great Teacher who Propagated the Dharma). Kukai is best known as the founder of Japanese Shingon Tantric Buddhism. The study is based primarily on writings attributed to him and his immediate followers and secondarily on early legends (those apparently dating from the Heian period) as identified by modern researchers. These writings show that Kukai was involved in a variety of social activities. In some instances I have attempted to understand the socio-political intention of Kukai's biographers, his followers and others. However, I devote more time to interpreting the biographical stories and Kukai's words in light of their literary, iconographic and religious images. I have based a large part of my own interpretations on modern iconographic guides, various encyclopedias and dictionaries of Buddhism.
