大般涅槃經義記 8.222

8.222

就寂靜中，先舉二數，「身心」列名。下辯其相，初先當法二門分別，下隨人異四門分別。當法辯中，兩義釋之：一約身心二惡分別。離身三惡名「身寂靜」，殺、盜、邪婬是身三惡。離意三惡名「心寂靜」，貪、瞋、邪見是意三惡。二約起惑始終分別。身寂靜者，不近四眾、不預四眾所營事業，離煩惱緣。心寂靜者，不集貪等，離煩惱體。隨人異中為開四門，下辯可解。

Regarding 'tranquillity': it first raises the number two, listing the names 'body and mind'. Below it explains their characteristics: first distinguishing them according to the intrinsic Dharma through two gates, and below distinguishing them according to differences among persons through four gates. In the explanation according to the intrinsic Dharma, it is interpreted in two senses: First, distinguishing them in terms of the two evils of body and mind. Leaving behind the three physical evils is called 'bodily tranquillity'; killing, stealing, and sexual misconduct are the three physical evils. Leaving behind the three mental evils is called 'mental tranquillity'; greed, hatred, and wrong views are the three mental evils. Second, distinguishing them in terms of the beginning and end of the arising of afflictions. 'Bodily tranquillity' means not approaching the four assemblies and not participating in the undertakings engaged in by the four assemblies, thereby separating from the conditions for afflictions. 'Mental tranquillity' means not accumulating greed and so forth, thereby separating from the substance of afflictions. In the differentiation according to persons, four gates are opened, and the explanation below can be understood.
