I find Sang Damanpal: Elements and Rhythms of the Self - Esoteric Yogi Wisdom - work exemplary.
The knowledge Sang shares clearly states the personal benefits of "enlightening an attitude and open perception." Supporting activities, exercises, work pages, tables, illustrations and other related topics made "Elements and Rhythms of the Self - Esoteric Yogi Wisdom a content friendly book simple to read.
One can take a glimpse of this genre of book, maybe read for the first time, and appreciate the beautiful artwork and photos. Esoteric Yogi Wisdom, lived and shared by Sang Damanpal, made the content of the book soothing, supportive of self, and others.
