I was thinking about Lokapalas, the 4 Guardians of Directions (=Dikpalas), and I caught an interesting, perhaps fortuitous, similarity to the group of main Norse gods. Could this represent somehow a common IE heritage? My point is not to state Norse deities as guardians of directions, but perhaps forming a particular tetrad.
Varuna (West) = terrible god = Odinn = terrible god
Indra (East) = storm god = Thorr = storm god
Kubera (North) = god of wealth, lord of aerial spirits (yakshas), owner of aerial chariot = Freyr = god of fertility, lord of elves (lives in Alfheim), owner of aerial ship
Yama (South) = King of the Dead, death God, first king, first man (substituting his brother Manu?) = perhaps Heimdall-Rig, perhaps Balder, perhaps benevolous side of Loki.
I'd like to read your comments.
