Send
On its scooter, a horned creature from heaven will take things you want to send there.
Picture the horned thing on its scooter, a big messenger bag over its shoulder with the kanji for heaven on it. "You got somethin' you want me to send?" it mutters.
そう
おく
None
You want to send your soul (そう) to heaven. I mean, you don't want it to go to some of those other places you've heard of, so why not send your soul?
You put your soul into an envelope, stick a stamp on it, and hand it off to be sent to heaven. Bye bye! I hope this doesn't have any negative effects on your body!
