So focussed to the ritual that everthing else seems merely an incidental is really quite a thing to be witness to. Yet in some other neighbouring central tribes menstrual blood is seen as a powerful aphrodisiac and is gathered in pots to be drank just like milk drunk directly from the cow for its unpasturised or homogenised goodness. There it is said , spanish fly and rhino horn just arent in it. So there it is cultural diversities all in a pretty mosaic and part of the larger intricate tapestries of the tribal world ever moving and ever changing to meet the ends of their own cultural needs. Or maybe they would all and at once be carried away into the ether by the silver jetted bird.
Speculation is only as prevalent as the conceptual.
Ill leave you now to chowdee down on it.
