What is left when a leaf dies and falls to the ground? The leaf slowly rots and becomes nutrients in the soil. The nutrients are drawn back up in to the tree to create new leaves. The form of a individual particular leaf is entirely erased. But what the leaf is made of continues. Einstein said that energy can neither be created nor destroyed, it only changes form.
If you got a face transplant and a name change you would still be you, because you is not the exterior form presented to the world but something deeper. If your ideas, thoughts and memories were to vanish, you would still be you because you is something deeper. I think that's what at least some of the theists are saying, and I suspect they are in some way right, just as the form of the leaf vanishes but the essence of the leaf continues.
It comes down to what we mean by the concept of "me". As we sit on the beach looking out to sea we can think of "me" as a particular wave moving towards shore, a form which has a beginning and an end. Or we can think of "me" as being the ocean, which is relatively eternal. While it seems more human to identify with the impermanent wave, it's perhaps interesting to observe that the wave doesn't actually exist as a "thing", it's just an observable pattern being driven by an invisible energy. I suspect we are much the same ourselves, a pattern in matter being driven by energy.
What "me" really is seems to be an illusion created by the inherently divisive nature of the information medium we are made of, thought. When you look out in your yard and see a tree, your mind gives the observed phenomena a name, thus
conceptually dividing it from the rest of reality. While this is a useful human convention we should keep in the mind that the tree is not actually divided from reality, it's not a separate thing, but is instead one with a single holistic reality extending out to the edges of the universe. The separate "things" we see are not a function of reality, but of the nature of the tool we use to observe reality. "Me" is likely no different, a useful illusion.
Thus, don't worry about dying, because you don't actually exist as a separate thing to begin with. Jesus may have been trying to say something like this with his advice "die, and be reborn". In those moments when we are able to completely surrender "me", in those moments when we are psychologically dead, nothing bad happens. In fact, these are some of the most joyous moments of our lives.
If you observe very closely and carefully you will see that we are seeking such a psychological death on an almost moment to moment basis throughout our lives. It is these moments of death when the tiny little prison cell of "me" vanishes that makes life worth living.
But, agreeing with this is of little value, one has to do the homework and patiently observe, and see it for oneself.
If the things we want to hear could take us where we want to go, we'd already be there.
