[M]eat itself always derives from killing.
If there were no killing,
the lives of animals would remain unharmed.
If there were no meat-eater, there would be no killer.
— Shambhala King Pundarika
(Vimalaprabhā: Great Commentary On The Kālacakra)
In the Mañjuśrī Pradarshana (Teachings On Mañjuśrī’s Own View), this is taught,
Killing beings for money —
if no money were given, no killing would happen.
Both parties have a genuine link between doer and deed,
and are always killers of animals.
If a fish were bought with money
and the householder had no wrongdoing,
then how could Buddha images and so on
generate any merit? …
When a fish is eaten,
if the eater has no wrongdoing,
then when a stupa is worshipped,
the worshipper will have no merit.
Devoid of compassion, monks who search after
tastes of meat to bring to their tongues,
whether they are fully ordained or novices,
they will bear themselves the sin of killing and so forth,
and be damned to hell.
— Shambhala King Yashas
