This valuable study guide is a comprehensive index to the fifteen books comprising The Collected Works of Eugene Halliday. Born in 1911, he was an artist, writer and psychotherapist who drew on many traditions of human knowledge and experience: the texts of world religions; mystical schools such as Qabalah; poetry, philosophy and theology (Blake, Milton, Nietzsche, Boehme); psychology (Jung) and modern science (Einstein). He formulated a psychotherapeutic method from which many were to benefit in the years following the second world war, and which is still of relevance and benefit to us today. His books form a comprehensive guide to self-development, both psychological and spiritual; and an interpretation of the wisdom tradition, East and West, for modern students of consciousness studies, philosophy, psychology, science, religion and hermeneutics.
