Why exactly do you say that there can't be two Karmapas? The famous Jamyang Khyentse Wangpo Rinpoche had at least five tulkus. There are numerous other lines of tulkus where there are more than one. Another example are the three lines of Pema Lingpa tulkus: Body, Speech, and Mind.
I'd just like to know your reasoning for saying that, when it comes of the Karmapa, there can be only one valid tulku. Thanks.
Also, Tulku Urgyen said there could be two Karmapa's, already from the beginning.
When I say there is only one Karmapa, this as a matter of fact, rather than a statement of what is possible. I don't mean to deny there could be two Karmapas. This is possible - when it comes to Karmapa, many amazing things are possible. I do not say 'there can be only one'. What I mean is, in the particular case of Orgyen Thinley Dorje and Thinley Thaye Dorje, one of them is a fake. It does not follow that there could not ever be two Karmapas at any point in time.
And the reason I think one of them is fake is that nobody - neither Orgyen Thinley nor Thinley Thaye, nor their gurus, not any high Kagyu gurus of the past, say that both of them are Karmapa. If these high lamas changed their views and said there were two Karmapas, that would change things. But to say there are two Karmapas is to contradict what all the high lamas say. On what grounds can someone ordinary like me make such an extraordinary claim?
We must avoid hostility and respect the fact that both claimants have their authentic Kagyu lamas who say they are Karmapa. But there is no fault in saying that one of the claimants is a fake, for this is to agree with what all the high lamas say.
