Grande is Buddhist erudition of the author and admirable his long search for a speakable justification for us (is?) Convinced of the value and share its experience of nirvana that we would certainly know all be it, like him, by the use of products that the author encourages us to consume shockingly here !! LOL. Seriously, if we do not doubt that his former enviable "thunderbolt" (undeserved! Lolilol) could properly and permanently inform his worldview, this is tedious and messy nth presentation of doctrine which can be found much clearer at Suzuki, he cites, especially, for the curious neophytes at Alan Watts, Robert Linssen or Dürckeim whose well-known writings take longer to reach our standard Western spirit of the approach. And there is no need to justify it, to fetch a dubious historical and philosophical link with Greek thought, which could make the questionable value of the original experience of Buddha in the eyes of the unbelievers. Enlightenment is an experience; that of H.Clerc, so sudden, would be better informed by simple theories of Zen which one consensus that the practice represents the most authentic because the pure, never crowded these texts by which tradition Indian has turned the eyes of all his object against an idolatrous religion which Buddha himself had however warned his direct disciples, and the exoticism that Western attach it turns into folklore. Conclusion: just practice with our own tools (but not dope, anyway!).
