大般涅槃經義記 2.171

2.171

第五汎明立制意中，「一切立制各有異意」，總以標舉，下別顯之。言「異意故聽食三」者，意為斷却餘不淨肉，言中聽食三種淨肉，心與言別，故云異意。言「異想故斷十種」者，想猶意也，為欲於彼三種淨中以漸遮斷，是故且言斷十不淨。此異前意，名為異想。言「異想故一切斷」者，為欲於彼十種之外一切悉斷，故今宣唱九淨亦斷。此乃異前漸斷之想，故復稱異。

In the fifth section, explaining in general the intention of establishing prohibitions, 'All established prohibitions in each case have different intentions' is a general heading, and below it is explained separately. The statement 'Because of a different intention he permitted eating the three' means the intention was to cut off the remaining unclean meats, while in his speech he permitted eating the three kinds of clean meat; the mind was distinct from the speech, hence it is called a 'different intention'. The statement 'Because of a different thought he prohibited the ten kinds': 'thought' is like 'intention'; because he wished to gradually prohibit [meat] from within those three kinds of clean [meat], he therefore temporarily spoke of prohibiting the ten unclean meats. This differed from the previous intention, so it is called a 'different thought'. The statement 'Because of a different thought he prohibited all': because he wished to cut off everything outside of those ten kinds, he now proclaims that the nine kinds of clean [meat] are also cut off. This differed from the previous thought of gradual cessation, and so it is again called 'different'.
