Only if we beg the questions of whether the soul is indelibly human and whether it's physical.

To be "remains", it needn't be indelibly human, just originally human. (e.g. cremated ashes).

I don't think the rule specified that it had to be physical remains, although that would certainly make it easier to package.

Some niggling little thing in the back of my mind is saying human remains are one of the few things explicitly prohibited by the US Postal Service.

Huh. I hadn't seen that yet. Sorry for repeating what you said!

Is the soul originally human?

And if not physical remains, why would anyone be worried about whether the post will ship it?

To answer those questions conclusively, you'll have to write to the Postmaster General.
