The Paradox of Transitoriness.
The paradox is that the idea of transitoriness can be depressing, but the experience of transitoriness is inspiring.
This is a clue as to the fact that meditation is not thinking.
Thinking is an activity of the neo-cortex. "Experiencing" is an activity of the sub-cortex. Recent research on trauma has clarified this: "The most self-regulating of all systems are the lower brain structures that govern life in the body.”
So, the very essence of "spiritual work" is trauma treatment. When you are successful in neutralizing trama imprints, you become open to your ultimate self-hood. Your ultimate self-hood is transitory. Yes, Jesus rose from the dead, but the account reports that the disciples were in the upper room, "the doors being locked for fear of the Jews (John got anti-semitic in his old age), and Jesus came and stood in their midst." So, do you have a body like that? I don't think so. So, whatever was going on there, it was not this body, it was not life-as-usual.
