If we are all to be one, does that mean one spiritual entity? Absorbed into the great I AM? If so, we'd be kind of like an ant colony where the overall 'colony-entity' is what matters. If one ant dies, the colony forms around that gap and continues; a newly born ant fits in the same way, the colony 're-forms' around it and it's now in its place. The colony is what matters and not each individual ant. (Ants may have a totally different take on this!)
What happens to a crippled or maimed ant? What happens to a rogue ant, a lazy ant, the rugged individual ant?
