What is the Big Mind/Big Heart Process?
Big Mind/Big Heart is an interactive process that integrates wisdom from Zen Buddhism with insights and tools from Western psychology to help participants explore their deepest sense of meaning and purpose in life. The process uses techniques from a psychotherapy process called Voice Dialogue, developed by Hal and Sidra Stone. The Big Mind/Big Heart process is intended to help participants transcend limiting self-concepts and attachments to experience the freedom and wholeness that comes with realizing one’s true nature. Big Mind/Big Heart is compatible with any faith or belief system, and participation does not require experience with Zen.
