At that time, Arya(sage) Mahamati(Great Wisdom) Bodhisattva-Mahasattva said to the Buddha:

"Bhagavan(World Honored One), I see that in all worlds, the wandering in births and deaths, the enlaced animosities, and the falling into evil paths, are all caused by meat eating and cyclical killing. Those behaviors increase greed and anger, and make living beings unable to escape from suffering. That is truly very painful."

"Bhagavan, people who eat meat are destroying the great merciful seed of their own, thus the people who practice the holy Way should not eat meat. "

~ from Lankavatara Sutra, translated during the Yuan,Wei Dynasty by Tripitaka master Bodhiruci from India
