Amogha Pasha, a trantra which focuses on the four-faced Avalokiteshvara
and belongs to the Kriya tantra, says:
Alcohol, meat, garlic, wild garlic, leek--alone or mixed with other
food--should be especially shunned. And: Those who wish to keep
the precepts must abstain completely from alcohol, meat, onion,
leeks, and the remnants of the offerings to the gods.
