bhaga, bon:ga

bhaga = "dispenser" , gracious lord , patron (applied to gods , esp.
to Savitr.) R.gveda; Skt. lexicon adds: Zd. {bagha} = Old Pers.
{baga} ; Gk.Slav. {bogu} , %{bogatu} ; Lith. {bagotas},{na-bagas}.]

There is a Santali (Munda) word: bon:ga which also refers to a
divinity,. e.g. sin: bon:ga = sun god.

Could these be cognates? If so, did Munda have borrowed the word from
PIE or IE or Indo-Iranian?
