Rosemary and I visited nearly every famous teacher in Thailand, and we also visited many of the famous Burmese teachers. There's nobody we can say for sure is an enlightened person. Whether there are some other enlightened people hanging out in caves or obscure monasteries, it's always a possibility. Whenever we hear somebody speak very favorably of a teacher we try to go visit them as quickly as we can. But as to whether there are any alive today, I can't tell you that.
