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.

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.
