I don't know anything about his personal life, but I have two of his books. The first one I've had for a number of years--would have re-sold it, but it has no value on the market. I'll probably donate it. The techniques he suggested in that book did nothing for me. For QiGong, I do suggest either Spring Forest QG or almost anything by Ken Cohen--especially his many cds from Sounds True. (In fact, I prefer Cohen to SFQG for my personal use.)

The second one is Soul Wisdom, and it came via Amazon's Vine program--and here it sits, awaiting my review of it. The procrastination bug has dug in deeply, because frankly, it's a stinker. Or perhaps I should say, it's really not to my taste. He repeats things over and over until at one point, I thought I'd lost my place and was rereading an older passage. But no, I guess it's just his style. Other people's mileage may vary, but none of his material works for me, even with repetition. ;\)

If you want to try his books, wait a bit, and the price for used copies will come down to practically nothing. I think some are now selling for a dollar or less. That way, you can sample his material and see if it's to your liking without making much of a cash investment.
