Psychic Deadness [PDF ebook] 

Many people seek help because they feel dragged down by a sense of inner deadness that persists in an otherwise full and meaningful life. These individuals somehow remain untouched by their own inner experiences; a deadness persists that can cripple their entire life or part of it. This book shows what is involved in enduring and working with psychic deadness in a day-to-day, session-by-session basis.
