Point of view is all-important to the human whose awareness lies across the veil from the All, which contains all points of view.  To the All, there is no-thing and all-things.  Things come and go, arising from pure Be-ing, going outward to have experiences, and then dissolving back into the no-thing-ness, which is not nothing but All-things-ness.  So, when you see things and people come and go and you despair, that is because you are stuck in the point of view that you are only one of those things. You need only shift your view back to the limitless, timeless nature of Being, from which you, the human arises, and voila – there You are again and again and again, never truly dying, simply resting in Being until the next adventure Here and Now.  Fear not.  You cannot disappear.
