The Dutch breathing therapist and teacher Cornelis Veening (1895–1976), who was active in various places in Europe, pioneered his own methods. This book contains excerpts from his letters and lectures, numerous recollections and statements by his students, and contributions from contemporary breathing therapists and teachers concerning his life and work. The book attests to the uniqueness and contemporary relevance of Veening’s approach to breathing therapy, which mainly revolves around the experience of the invigorating body-soul forces of the Inner Breath. This in turn incites change that gives rise to individual awareness processes and promotes self-development, both from within and outwardly.
