I thought it was a terrific read. Since I'm 58 and have been meditating since 1975 I have read / study / visited many of the visionaries and scoundrels covered in his book. It also gave insight into what I have missed. I consider his book the Cliff Notes to Vedanta or a Michelin Guide, if you will.
As a great companion piece I would also recommend The Harvard Psychedelic Club which cover the journeys of Houston Smith, Andrew Weil, Timothy Leary and Ram Das.
