As a Monist, I believe that is the ultimate goal: Nothingness.
That is the only way to be complete with All as One again.... in the Nothingness. It is all the same. Life and death are the same thing. One does not exist without the other, when one looks beyond the duality of our place..... they find the ONENESS of ALL and NOTHING. It is the same in the end.
There is nothing to fear from death, regardless of what the next life or non-life holds for "us", "you", or "I". In then end/begining.... it is all the same: for there is no end or begining.
I once did a poll of many of the people I know. I asked how they would like to die. Over 95% said they wished to pass "in their sleep" so they would not know. I wish to die with "eyes wide open". Death is the last expirience life can give. Why would one not look forward to it? To the next life or the last moment they could have?
Either way...... the first moment of the next or the last that one could have..... why would you be afraid to behold that moment? It matters not what it is, for it is both sides of what one makes it..... and more.
(As for global warming in this conversation: the Earth will be gone with the solar system in a few billion years..... the galaxy in about 15 more...... what does a few hundred year process in the making matter?)
