注大乘入楞伽經 9.94

9.94

This explains that anyone who says that the Buddha permits the eating of meat in the Vinaya is entirely slandering the Tathāgata. Formerly, in other sūtras, when ten kinds were forbidden and three kinds were permitted, it was because sentient beings' evil habits had been long established and their desires could not be removed all at once; it was a gradual prohibition, formulated in accordance with their dispositions so as to train them. Now, in this assembly, under all circumstances and at all times, provisional permissions and prohibitions are entirely terminated; this is called the final, pure, and clear instruction. As for forbidding the ten kinds, they are: human, snake, elephant, horse, dragon, fox, pig, dog, lion, and monkey. Permitting the three kinds means: not seen, not heard, and not suspected. This means meat is of two kinds: killed by another, or died naturally. What is seen, heard, or suspected is what is killed by another; what is not seen, heard, or suspected is what has died naturally. Or some say five kinds are permitted: besides not seen, heard, or suspected, adding what is left by birds and what died naturally to make five kinds. Although the three and five are spoken of differently, neither departs from the single meaning of meat that died naturally.
