首楞嚴義疏注經 6.384

6.384

「汝等當知，是食肉人縱得心開似三摩地，皆大羅剎，報終必沈生死苦海，非佛弟子。如是之人相殺、相吞、相食未已，云何是人得出三界？」

"You should know that even if such meat-eaters attain an opening of the mind resembling samādhi, they are all great rākṣasas. When their retribution ends, they must sink into the bitter sea of birth and death; they are not disciples of the Buddha. Such persons kill one another, devour one another, and feed on one another endlessly; how could such people ever escape the three realms?"
