Hence the terminology 'Tulku Disease' which literally means the 'degeneration' of that life so to speak. I was also told that this does not necessarily mean their mindstream is effected. They are still able to 'return' I am told. Is this right?
I can see how this happens as a Tulku actually has gain attainments to have control over his/her rebirth but is not necessarily 'attained' (if that makes any sense). Control over rebirth is merely a 'side effect' of certain practices and hence even though it gives them the opportunity to reincarnate in an opportune life, it does not by any means it will be 'easy'.
Please correct me if I am wrong with regards to the above.
From what I have heard from my Lama... there are basically many levels of "Tulkus". Some are stronger and some are not so strong...this I take to mean their mind stream and their attainments as there are also many levels of attainments just like many levels of Boddhisattvas. Their main purpose is to continuing their practice and their work in spreading/teaching Dharma when they have incarnated back.
So for those that are not so highly attained, if they are not nurtured properly with the right conditions/education/care, that does not direct them to their main purpose for incarnating...then they may manifest the "tulku desease". However there are those that no matter where they take rebirth or how difficult the situation is for them, they will actually persevere and overcome them to achieve their destiny.
I have read some books, can't remember off my head now, that the " tulku desease" could manifest in a form of mental sickness, like acting crazy and or even dying young. This is simply because what they came back to "samsara" for was not achieved...they have no other purpose but to spread the Dharma and continue their practice, hence if they are deprived of that, their lives will be cut short so that they can take on another new rebirth where the situation allows or supports them to pursue their destiny. That is what I know so far.
Has anyone actually witnessed or seen a "tulku disease" before?
