This article describes an art-based approach to supervision that combines clinical insights with archetypal awareness arising from painting on a single canvas throughout the internship semester. Supervision is comprised of three main components: (a) spontaneous painting, (b) complex reflective processing, and (c) aesthetically focused attention to imagery appearing in the painting that parallels the internship experience. Inspired by the artistic struggle of "el duende" to bring forth emotional vibrancy, a central aspect of the model is the supervisee's relationship to a single canvas that transforms awareness through sequential layering, that welcomes tension, and that potentially integrates personal and professional identities.
