See Chögyam Trungpa, Cutting through Spiritual Materialism, for take one. And BTW: if you haven’t seen the biopic of Trungpa, Crazy Wisdom, it’s exceptionally well done. He knew very well the farcical aspects of “being a guru” to gullible westerners.
We all took Trungpa’s book very very seriously, of course. Hmmm. Just when did I start pronouncing “New Age” as Neuwaaahge?
