摩訶止觀 9.131

9.131

若通論發者，一一禪中皆能發五通。若就便易別論者：根本多不能發，設發亦不快利。特勝、通明多發輕舉身通。背捨、勝處多發如意轉變自在身通。若慈心定中緣人色貌，取得樂相，因色知心，識其苦樂，此多發知他心通。既藉色知心，亦知其言語音聲，亦發天耳通。因緣觀人三世，照過去事，多發宿命通；照未來事，多發天眼通。若念佛定不隱沒者，多發天眼通。

Speaking of manifestation in general terms, within each and every dhyāna all five supernormal powers can be manifested. Speaking specifically according to ease and suitability: the fundamental dhyānas for the most part cannot manifest them, and even if they do, they are not swift and sharp. The superior practices and the penetrating clarity concentrations mostly manifest bodily supernormal powers of levitation. The liberations and bases of mastery mostly manifest bodily supernormal powers of sovereignty in intentional transformation. If, within the concentration of loving-kindness, one takes the physical appearance of people as object, grasps their marks of joy, and knows their minds by means of their forms, discerning their suffering and joy, this mostly manifests the supernormal power of knowing others' minds. Having used form to know the mind, one also knows their spoken words and vocal sounds, which also manifests the supernormal power of the divine ear. If through causes and conditions one contemplates the three periods of people's lives and illuminates past events, this mostly manifests the supernormal power of past lives; if it illuminates future events, this mostly manifests the supernormal power of the divine eye. If the buddha-mindfulness concentration is unconcealed, it mostly manifests the supernormal power of the divine eye.
