I think it seems like if the Dalai lama were to re-transmit Trijang Rinpoche back the transmissions that he received from him, like Karmapa does to Shamar Rinpoche and vice versa, then I guess it would make it seem that Trijang Rinpoche would accept that the Dalai lama hadn't given the appearance of breaking samaya with him for abandoning the Dorje Shugden practice.
I think this is an important teaching; even if the Dalai Lama is a Buddha, he can still teach in reverse psychology; so he can give the appearance of breaking root guru samaya; so how could he transmit something purely if he really broke root guru commitments? (I am not saying he did or didn't as I am an ordinary sentient being and can't tell for sure who is a Buddha. But the Buddhas can manifest emanations that show incorrect behavior to help us learn, so that is possible that that is what the Dalai lama would be doing). So in other words, if a government (like China or any other government) were to pick a candidate for any tulku at all and he didn't even keep samaya with his root guru, then we wouldn't really consider that he could give the transmissions purely to the next incarnation. (Hopefully all tulkus will be Buddhas even if they are recognized by China, but I am just saying, right activity is to keep religion and politics separate).
So in other words, Trijang Rinpoche might be looking for someone who showed keeping root guru samaya.
I understand we are from different cultures who post here, and I honestly do not know who is a Buddha or not, but I am not sure why I am supposed to believe without investigation that a political leader is a complete Buddha.
I am from the west, okay, and if you tell me 'that guy is a Buddha,' well, you need to prove it. I notice though, that the Penor Rinpoche Nyinmgas and the Shamar Rinpoche Kagyus have never claimed that we had to accept without question that the teachers were Buddhas or that we couldn't question what they say. Actually, I have never seen any Kagyu do that, on either half of the lineage. As for the Nyingmas, the only ones I have studied with were Penor Rinpoche's ones.
I guess it is like when Christains tell me that I have to believe in Jesus or I am going to hell; I just don't buy things because someone says so.
I am praying that Trijang Rinpoche will help us get the ban lifted. If not, maybe it is so China will let us practice Dorje Shugden because the Dalai Lama is pretending he dislikes Manjushri when he takes this particular form.
