At the deepest levels, light doesn't reveal but actually conceals. Light pollution also accelerates the distraction epidemic, disconnecting us from ourselves, from each other, and from nature. The ancient practice of dark retreat helps us reconnect. Dark retreat diagnoses how we’re afflicted with a darkness deficit disorder, a disorder of depth, interiority, and authenticity, while simultaneously prescribing the cure. Dark medicine invites the deepest form of shadow work, sparks creativity, and allows us to find meaning, balance, and inner peace in our lives. The healing power of darkness leads to profound restoration and transformation, and a total reset for the nervous system. It’s the ultimate silent retreat, and therefore the deepest form of meditation. Facing your fears in the dark allows you to transcend them, nurturing a quality of fearlessness that extends into daily life. The mirror of darkness further shows you that who you THINK you are is defined by what you do; who you REALLY are is revealed when you finally stop doing. The embrace of darkness invites you to relax and discover who you really are, resulting in the experience of unconditional love.
