Today when I had a religion class about hinduism, I got to learn that Braham, is the name for a indian priest, and there happens to be a characters named Braham, one of the shandians with the dual pistols. It was quite cool that Oda gave him a name like that.
So anyone else got some references that you can draw in the OP verse? I believe we could find some really intresting stuff in this subject.
I know one more thing that some may heard from me before. Whitebeards weapon, looks like a Guan Do, a chinese war spear that was "invented" by Guan Yu aka God of War, very fitting to the most powerful man in One Piece.
EDIT: Ops, I was wrong about the brahamn part, because appearnlty the indian priests are Brahmins!
