俱舍論頌疏論本 18.28

18.28

釋曰：初者，謂世尊轉法輪未久。後者，謂佛將般涅槃。此二時中僧一味故，不可破壞。皰前者，皰謂瘡皰，於正戒上邪戒為皰，於正見上邪見為皰。皰未起時，名為皰前，要二皰生方可破故（五法是邪戒也，謗八聖非道是邪見也）。雙前者，目連止第一也，舍利弗觀第一也，名第一雙。未有止觀第一雙時，名為雙前。要彼和僧，法爾由彼速還合故。

Explanation: "At the beginning" means not long after the World-Honoured One turned the wheel of the Dharma. "At the end" means when the Buddha is about to enter parinirvāṇa. During these two times, because the Saṅgha is of one flavor, it cannot be broken. "Before the boil": "boil" means an ulcerous boil; heterodox morality is a boil on orthodox morality, and heterodox views are a boil on orthodox views. When the boil has not yet arisen, it is called "before the boil," because the split is only possible once the two boils have arisen. (The five dharmas are heterodox morality; slandering the eight noble paths as not the path is heterodox view.) "Before the pair": Maudgalyāyana was foremost in calming (śamatha); Śāriputra was foremost in insight (vipaśyanā); they were called the supreme pair. When the supreme pair of calming and insight had not yet arrived, it was called "before the pair." It requires them to reconcile the Saṅgha; by the nature of things, it is quickly reunited because of them.
