It would not be difficult to trace the quotes in his book which, as he writes, misrepresent the Buddha's teachings on mindfulness. In fact, if you have listened to his less formal Dhamma talks, he does drop a name or two occasionally... But his justification for presenting a valid criticism of teachings, not of persons, is well taken. It is based on the Buddha's instructions on How to Teach Dhamma:
Anguttara Nikaya 5:159
It is not easy to teach dhamma to others.
Concerning the teaching of dhamma to others, only after five things have been internally established is dhamma to be taught to others. What five?
1. “I shall speak a graduated discourse…“
2. “I shall speak a discourse that is insightfully-arranged…“
3. “I shall speak a discourse grounded upon caring…“
4. “I shall speak a discourse without motivation for personal gain…“
5. “I shall speak a discourse without disparaging myself or others…“
…thus is dhamma to be taught to others.http://www.dharma.org/ij/archives/2000b/ss_teaching.htm
