I stopped reading this book shortly after this paragraph:
"On the plane [from New Delhi to Amritsar] was a group of tourists, prototypical Ugly Americans wearing plaid shorts and golf shirts, with cameras around their necks, intent upon getting the 25-cent tour of the holy hot spots: first the Golden Temple in the City of Immortality, and then a quick bus run up the road to Dharmsala, the Place of truth, where the Dalai Lama lived. Then lunch, then shopping. Then dinner, then back to the New Delhi Hyatt, for CNN and the stock quotes." (page 101-102)
First of all, this paragraph is judgmental and lacking compassion or any attempt at empathy or understanding. Even if one believes that he actually saw tourists in plaid shorts with cameras around their necks, how can Khalsa know the intention of anyone except himself? All of this is his projection. He is the "Ugly One" rushing around India (and the world) looking for enlightenment. And second, he lives in the U.S. with all us Ugly Americans, not in India where he looks for holiness.
This book is about the practice of Kundalini yoga and there is nothing like the real thing - attend a class in this branch of yoga to experience fully the effects of chanting and mudras, posture and breathing. If you can't attend a class in your town, look on YouTube, buy a DVD, or see what's available at your library.
