The Esalen Institute, commonly called Esalen, is a non-profit American retreat center and intentional community in Big Sur, California, which focuses on humanistic alternative education. The institute played a key role in the Human Potential Movement beginning in the 1960s. Its innovative use of encounter groups, a focus on the mind-body connection, and their ongoing experimentation in personal awareness introduced many ideas that later became mainstream.
