This talk was given as a part of the series "Enhancing Mindfulness Skills: A Seven-Week Series Dedicated to Cultivating Transformative Insight." This talk focuses on "Four Elements." It is a traditional practice of mindfulness of the body. In ancient India, the materiality of the body was thought to be composed of four elements—earth, fire, wind and water. These four elements, in turn, have twelve characteristics—(earth) heaviness and lightness, hardness and softness, roughness and smoothness; (fire) heat and coolness; (wind) pushing and supporting; (water) fluidity and cohesion. All of these characteristics can be known with our mind and in our body. Discerning the characteristics of material elements will lead to a profound contemplation of impermanence and death. Seeing the impermanence of the body, we know we cannot control it. The body is not-self, it is not possessable, not I, and not eternally me. Understanding the impermanence of material elements and this body composed of elements, we learn to let go. This talk concludes with a guided meditation of body scans, with emphasis on the four elements and their respective characteristics.
