Nichiren’s fierce insistence on the sole efficacy of the Lotus Sūtra has not endeared him to modern scholarly commentators, who have often dismissed him as narrow and intolerant. Yet another aim of our volume is to show how Nichiren’s reading of the Lotus Sūtra made compelling sense in the context of his received tradition and his understanding of his own time; it illustrates how much can be at stake in the interpretation of scripture. Through his example, we demonstrate how what Lotus followers regard as an ancient and timeless revelation came to be deployed in a specific time and place – thirteenth-century Japan – in an effort to understand, and to transform, that time and place. Focusing on Nichiren allows us to provide a kind of case study of how an ancient Buddhist text was appropriated by someone in a very different historical and cultural context to address questions undreamed of by the sūtra’s compilers.
