Drawing on his own decades long, compassionate engagement with Indian yoga and Tibetan Dzogchen, Dr. Ifergan explores the full contours and scope of Patanjali’s integral yoga, including Patanjali’s higher order insights into the nature of conditioning, the yoga methods for deep healing and purification, and the peaks of yogic realization.
A particular virtue of this study is its presentation of Patanjali in settings that can be easily recognized by readers who have engaged in any form of psychotherapy or meditation, or who are simply reflecting deeply about their emotional lives. Psychologists, counsellors and psychotherapists who are looking to ground their work in a knowledge of yoga psychology, and it’s far reaching potential, will be richly rewarded in these pages. Certainly, readers who practice yoga with a knowledge of Patanjali’s eight-stage (ashtanga) system will benefit immensely from the attention given to practices such as “cultivating the opposite” and the use of creative imagination in yoga psychology.
From the Foreword by Dr. Peter Fenner, author of Radiant Mind and Natural Awakening

Reviews of the Hebrew edition of the book published by Resling Publishing in 2018:

An amazingly readable and persuasive book. I would like to thank the author for both the important study... and for the useful effort he has made to shed light on the dark side of enlightenment.
Ha'aretz: Book Supplement

Ifergan ...uses psychological concepts and enriches the reader with the yoga practitioner's experience. He formulates his words with deep understanding and familiarity with both of these fields of knowledge and offers us both theoretical and experiential learning.
