宋高僧傳 25.32

25.32

釋遂端，姓張，不知何從而來德潤寺求師。其為人也，質直清粹，不妄交遊。師授《法華經》，誦猶宿構，人皆駭歎。至乎老齒，勤而無懈——十二時間恒諷不輟。咸通二年，忽結跏趺坐而化，須臾口中出青色蓮華七莖。遠近奔走，皆至觀禮。邑人同心造龕，窆於東山之下。二十餘年，墳塋屢屢光發，後開視之，形質如生。眾迎還寺，漆紵飾之。今號真身院存焉。伊寺者，吳太子太傅都鄉侯闞澤書堂，後捨為伽藍，其題額取澤字也（今普濟寺是也）。

Śramaṇa Suiduan, surnamed Zhang, came from an unknown place to Derun Temple to seek a master. In personality, he was upright, pure, and refined, never associating with people casually. When his master transmitted the Lotus Sūtra to him, he recited it as if it were an old composition, and everyone was amazed and sighing in praise. Reaching old age, he remained diligent without slackening—throughout the twelve hours of the day, he chanted constantly without stopping. In the second year of the Xiantong era, he suddenly sat cross-legged and transformed. In a moment, seven blue lotus flowers emerged from his mouth. People ran from near and far, all coming to view and pay reverence. The local people united to build a shrine and buried him beneath the Eastern Mountain. For more than twenty years, the burial mound repeatedly emitted light; later, when they opened it to inspect, his form was as if alive. The community escorted him back to the temple and adorned him with lacquer and ramie. Today the True Body Cloister remains there. That temple was originally the study hall of Kan Ze, Grand Tutor to the Crown Prince and Marquis of Duxiang of Wu, who later gave it up to become a saṅghārāma; the title on its plaque was taken from Ze's name (which is present-day Puji Temple).
