You do realise that some (most) conventional medicines are poisonous when used incorrectly, at the wrong time, for the wrong disease, by the untrained? Why do you believe that spiritual medicines would be any different?
Indeed, and do doctors tell you "come attach yourself to me, so and one day I will teach you the super special secret medicine to cure all your ills!"? Or do they just go ahead and administer the medicine?
Are you saying that it is unrealistic to check a teachers conduct and their practices, before giving yourself over to them, in order to avoid later apocalypses which may lead to you abandoning them and the practices? I mean, that is what I, personally, would be proposing.
Why no, this is not unrealistic at all! But how can you do this if their practice is super secret?

Right right, but some of the deities come from Tibet, and Tibet's pre-buddhism religion was adapted and incorporated into the new one, much like we saw happen with big name western religions.
