[1] It focuses in detail on eleven pioneering figures of the transformation of yoga in the 20th century, including Yogendra, Kuvalayananda, Pant Pratinidhi, Krishnamacharya, B. K. S. Iyengar and Indra Devi.

[2] The Path of Modern Yoga, based on what the author states is 10 years of research, examines the history of modern asana-based yoga through the lives of eleven pioneering figures: Sri Yogendra; Swami Kuvalayananda; Seetharaman Sundaram; Tirumalai Krishnamacharya; Swami Sivananda; the bodybuilder K. V. Iyer; the rajah of Aundh, Pant Pratinidhi; the journalist Louise Morgan; the diplomat Apa Pant; and two students of Krishnamacharya, his brother-in-law, B. K. S. Iyengar, and one of Iyengar's pupils, Indra Devi.

In Remski's view, along comes "Goldberg with a dozen years of dogged research, a sleuthing style metered out in engaging chunks, a deep appreciation for the embodied sensations offered by competing visions of asana practice, a sharp eye for human foibles and historical oddities" and "makes a bold attempt to ride the elephant.

As blindfolded as everyone else, he wobbles a bit, but hangs on for long enough to produce something that a lot of people have been waiting for: a penetrating, body-aware cultural history of a modern spirituality, written through richly realized characters."
