I don’t think I need to abandon my individuality to melt into the Universe. But I have no idea what happens after I die.
If I melt into the Universe instead of maintaining my individuality, what would that mean? That “I” am lost in some big energy soup, with all my memories and emotions gone?
If that *does* happen, I might not like the idea now. But I wouldn’t care about it then - because “I” would be gone.
2000 years ago, roughly, there is a man who showed us that to die is not to lose individuality. He stayed dead for three days, then arose to everlasting life. Implicit in those notions are levels of what it means to ‘be alive’. i won’t bore you with lengthy biblical exegesis, suffice it to say there is more to life than merely the functioning of cells and chemical activity as we sense it.
