That's fine Malcolm.
I have emailed Tergar's Tim Olmsted to inquire about this,whether or not Loch Kelly has been authorised or not. Philji PM'd me and clarified this based on what he knows.
Be it one way or the other, on the basis of my familiarisation, I certainly would not be as hasty as Malcolm calling Loch Kelly "new age". He's been studying with these rinpoche's for a few decades. A person like that doesn't become new age overnight simply because the lama's permission isn't there after all. I've heard only good things about how Loch teaches and how people benefit of it.
Even if it turns out that he misunderstood something and did not receive Mingyur's permission, it doesn't make him a hoax. Perhaps he simply misunderstood, got something wrong. I doubt, though can't be sure, that he purposefully started to mislead people and claimed authenticity as a mahamudra teacher while Mingyur was on retreat. Even if he is, well, keen on money it doesn't make him a liar and a false guru. After all, he has studied with Mingyur, Tsoknyi and Tulku Urgyen for a long time. I still consider him very worth checking out, with or without Mingyur's authorisation. I still think his interviews and materials are very beneficial to any student of meditation. This is something that can't be said of many lamas out there who have formal credentials bigger than a house.
”I don't think we need even a scrap of Tibetan culture, including vajrayana buddhism, in order to recognise the nature of mind. If somebody walks in of the street here who never heard of Tibet or Tibetan buddhism and has a natural antipathy to anything other than American culture, is given the essence of dzogchen, there's no reason why that person should not attain immediately the same state that we have reached, having gone through that whole circuit of oriental culture and Tibetan buddhism.” - Keith Dowman
