Thank you for taking the time to reply to my question with great links and by pin-pointing your problem with Bhante V. I, too, find it troubling but do like the technique. You mentioned you were familiar with other teachers who employ a similar "smile and relax" method and, if you happen to remember them and don't mind sharing their names I'd appreciate it.
To avoid all evil, to cultivate good, and to cleanse one's mind — this is the teaching of the Buddhas.
