IF you go to HARDWAAR on the Banks of the Ganga..you will meet a TRIBE of SADHUS who EAT rotting/half burnt HUMAN CORPSES... they will swim out to the burning pyre..and eat their Fill..its a RELIGIOUS OBLIGATION and LAWFUL.

BTW imho asking IF Cannibalism is allowed by GURBANI is as SICK ...or even...as sicker than they come. What has Cannibalism got to do with SPIRITUAL JOURNEY which is what Gurbani is about ??
