The Gnosis of Artmaking and Teaching: Painting the Blue Medicine Buddha by Sally Gradle (2009) Educational Insights 13(2).

Abstract

In this short work, I begin by exploring gnosis as a way of knowing that is direct, embodied, and embedded in the active imagination that is so essential in teaching and art making. As an artist and art educator, I utilize the phenomenological process of shikantaza, or “just sitting” as a methodology of witness. Second, I consider how compassion as a way of knowing can develop within a cosmology that recognizes the dependent, relational quality of everything that manifests. Last, I propose that releasing as a way of knowing opens the teacher and the artist in the most profound way to understand the experiences that occur in the classroom and beyond. As a parallel text, I offer three artist journal insights, composed as I worked through the process of presenting the Blue Medicine Buddha in a painting.
