I must get a copy. His mother's book 'The mother of God' by Luna Tarlo is quite interestng and an easy read also though there is really no similarity between her situation and Mata Ji's.What Is Enlightenment (see http://www.wie.org/ ) is on a much higher intellectual plane than anything related to Elan Vital so it is intersting to see Joe's description of Cohen taking to his followers. In the end all of these groups seem to revolve around gurus being adored by followers.
Just cause he doesn't regret his involvement is not a copout. Maybe I haven't let go of all my vedanta ideas but you might as well accept your past, use it to the best advantage and let it go.
