One of the most influential yet concise works in the history of psychology, Self-Mastery Through Conscious Autosuggestion introduced the world to the extraordinary power of the unconscious mind. In this modern English edition, Émile Coué's timeless insights are rendered in clear, accessible language, free from the stiffness of early translations. Coué reveals how simple, repeated affirmations—consciously directed—can rewire the unconscious, overcoming fears, habits, and even physical symptoms. He explains the 'law of reversed effort,' why trying too hard often backfires, and how to harness the imagination for healing. Practical and profoundly humane, this book offers a method that anyone can use: a series of daily autosuggestions that build resilience, confidence, and self-command. Whether you are struggling with anxiety, chronic pain, or simply seeking greater poise, Coué's gentle technique provides a path to lasting change. This edition includes a biographical note, glossary, and reading guide to deepen your understanding. Part of The Modern Wisdom Library.
