yes, tibetan buddhists have the bardo to contend with the 49 days and three phases as described, and as described, some tibetan buddhists feel that the bardo state is real, and Shinje really does count out the pebbles, some tibetan buddhists feel that the bardo is the product of illusion within the mind, and can be overcome, with the consciousness unwavering, although this is difficult, apparently, but, if acheived, a person, or usually, great lama, will not only be reborn but will also decide upon their own incarnation, but not all buddhists see it like that, of course... Some buddhists (the pure land school) feel that by simply by chanting or even remembering the name of Amitabha upon death one will be reborn in a pure land, bit like heaven, even if a person knows no other buddhism, some buddhists would chant other mantras, or perform sadhanas (specific ritual prayers, kinda) to say, a peaceful goddess, such as Tara, or perform the medicine buddha puja...
however, other buddhists might say that all this is nonsense, and death, like everything else, is an illusion, and the buddha taught ppl about the nature of impermenance, not to depress them and instil futility within them, but to expose the idiocy of the notion that we are immortal, that there will always be tommorrow, we can put things off, et cetera, and also to create within ppl the desire to be seperate from their bodies, and their baser desires, and to become more mindful... most ppl do not sit and ponder about death until it is too late, when they are staring in its face, and fearing it, and ppl should contemplate their own impermanence and there being no them in the world as it just might inspire them to greatness..
yet, personally, as a human being, I would comfort the dying in this way...
I would be frank, and bring up the topic of death... it might be a relief to talk about it... if the person didnt want to discuss it, I wouldn't, but if they did, I would say that although buddhism suggests that death is an inevitable part of life, it need not be feared... I would ask them of their faith, and perhaps pray with them, if they were able... I would tell them that when our time comes we know it in our hearts, and if the person feels that it is time, then they should be reassured that their loved ones would be looked after, that there were no sins that would bar them from the bliss that lies beyond this life, and to remember that they lived, and touched many ppl, and as we lived we shall still live, in the hearts and minds of others, treasured, and I would encourage the person to discuss with me what they wanted to beyond that...
might not be what the Buddha said, but its the best I can do...
