This
was said by the Lord...."Bhikkhus, if beings knew, as I know,
the results of giving and sharing, they would not eat without
having given, nor would they allow the stain of meanness to
obsess them and take root in their minds. Even if it were
their last morsel, their last mouthful, they would not eat
without having shared it, if there were someone to share it
with. But, Bhikkhus, as beings do not know, as I know, the
results of giving and sharing, they eat without having given,
and the stain of meanness obsesses them and takes root in
their minds."
