Can sweeping the floor or scrubbing a sink unlock the secrets to a peaceful mind? For Shoukei Matsumoto, a Buddhist monk and author rooted in the Japanese Zen tradition, the affirmative answer lies in the profound simplicity of these acts. Armed with a broom and an ancient philosophy, Matsumoto has captivated minds with an unexpected revelation: cleaning isn’t just housekeeping—it’s soul-keeping. His bestselling book, A Monk’s Guide to a Clean House and Mind (translated into multiple languages), invites readers to reimagine daily chores as spiritual practice. By emphasizing that outer order fosters inner clarity, Matsumoto reveals how rituals of simplicity can help us navigate the chaos of contemporary life.
