I'm guessing it doesn't have to be in one person

I would put money on after he completes all he becomes balanced an sane again. My other money would be his daughter or wood lady snaps him back to reality.

Hopefully it's not that cute wood lady gone mad

But that's probably just my spin on it.

Remember the hero spring? What would you prefer? Holy water or chieftain golden shower.

I was wondering about the translation inconsistencies

It's not with each other ... mostly

Buddhism developed out of Hinduism. Reincarnation cycle and so on. Some hindu gods appear in buddhistic mythology, if I remember correctly. 
Let's say close enough. Better would have been:
I don't know which gods you believe, but I hope you prayed enough to them for your next life.
