In my research for my book on mindful composition, I recently came across a marvelous article, Erec Smith's "Buddhism's Pedagogical Contribution to Mindfulness," in the Journal of the Assembly of Expanded Perspectives on Learning: http://trace.tennessee.edu/jaepl/vol21/iss1/7/
I highly recommend it! I recommend the article, hoping you have access to a library database.
In part, Erec Smith examines the Lotus Sutra as a rhetorical treatise. He also makes connections between mindfulness, Kairos, and critical thinking in the writing classroom.
