Okay, so in response, I would say I definitely don't take the DL in a guru-disciple relationship way at all, and never did. I understand too, the very good point, that if a teacher stops relying on his lineage then it doesn't make sense to follow him, because a valid teacher doesn't work that way.
The issue though, from my perspective, and I feel compassionate and sorrowful that this is happening in our world on such a large scale, is that people are being mistaught the tantra by the DL. So, this whole thing where he is giving tons of people the initiations of Kalachakra and then going on to tell them to stay away from Shugden practitioners, and then people say, oh he is just being wrathful with his compassion, the problem is that they didn't yet become advanced enough practitioners in most cases to even vaguely observe the 'guru' the right way, and so started relying on a not so valid guru.
It is okay, if you think you made a mistake, to find a teacher you think is valid and ask for advice on how to handle this sort of thing. (Actually, the valid gurus will probably tell you that you don't have to keep samaya with someone who isn't able to give it or something.... or they will help you in some other way, depends on the guru). It is really a mistake for the DL students to run around the world thinking they are high practitioners; a lot of people can take tantric vows in various lineages but we know just because we got this vow doesn't automatically make us qualified.
In Tibet, before the time of Atisha, there was a lot of misuse of tantra, but of course it would be hard for one person to use it worldwide back then.
I think that people are mixed up because if they thought the DL was a Buddha because everybody said so, and they read a book and he seemed nice, even if the thought passed through their head, and they went and took Highest yoga vows, well, I think they didn't really get a chance to examine the guru, or frankly, at least in recent years, they would have known better to take it in the first place.
I myself cannot give anyone tantric samaya, as I don't happen to be qualified. So if I said I could, and I couldn't (may I never do such a henious act) then of course, a valid teacher would just tell you you know that person can't give samaya. So, please, understand that this would hold true, anytime the person isn't qualified.
