1.8.52

यथा पङ्केन पङ्काम्भ: सुरया वा सुराकृतम् । भूतहत्यां तथैवैकां न यज्ञैर्मार्ष्टुमर्हति ॥ ५२ ॥

yatha pankena pankambhah suraya va surakrtam bhuta-hatyam tathaivaikam na yajnair marstum arhati

yatha
as much as
pankena
by the mud
panka-ambhah
water mixed with mud
suraya
by wine
va
either
surakrtam
impurity caused by the slight touch of wine
bhuta-hatyam
killing of animals
tatha
like that
eva
certainly
ekam
one
na
never
yajnaih
by the prescribed sacrifices
marstum
to counteract
arhati
is worthwhile.

As it is not possible to filter muddy water through mud, or purify a wine-stained pot with wine, it is not possible to counteract the killing of men by sacrificing animals.
