"Eric somehow manages to distil a lifetime of experience, spiritual practice, and psychological learning into a very accessible, comprehensive model of human psychology and behavior. Not since Ken Wilber have I read such a concise and useful synthesis of psychology, spirituality, and ecology. I find it incredibly useful in my work as a therapist and as a guide on my own spiritual journey."
-Richard Chambers, PhD, Clinical Psychologist
Co- author of 'Mindful Learning'

"Essential Wholeness is a living, breathing book that has opened up the vast potential healing impact of my work with clients. Lyleson offers us his life's work, drawing deeply and compassionately from thirty years of clinical work and his direct experience to offer a highly original contribution to the way we understand change and the experiences of being human. This book travails a vast territory, from cutting edge scientific thought to the wisdom traditions, challenging the reader to continually open to deeper and deeper levels of understanding and insight. This book is like no other that I have read and presents a clear way forward in my evolution as a therapist."
-Justin Denes, MAASW, Accredited Mental Health Social Worker
