... I've never heard of, seen, or am aware of such a thing - ua tsaug tso plig - in all of the funerals and spirit releasing ceremonies I have ever attended. Nor have I ever heard any of the elders mention or talk about it. It is plausible but never experienced/seen it first-hand. And during a "tso plig", normally it is just the immediate family members and close in-laws, thus there are no "donation" etc. - none I have seen/witnessed that is.
