妙法蓮華經玄義 6.65

6.65

三、明神通不同者，鬼道報得通；人能服藥亦得通；外道因根本禪亦發通；諸天報得通；二乘依背捨勝處一切處，修十四變化發得神通；六度菩薩因禪得五通，坐道場時能得六通；通教菩薩因禪得五通，依體法慧得無漏通；別教地前依禪發五通，登地發正無漏通，任運常照，不以二相見諸佛土。圓教通者，依今經及《普賢觀》，以鼻、舌兩根，以為六數。《菩薩處胎經》同：他心、宿命入意根攝。然經文明「鼻通」最委悉，取其互用無壅。舌根，取四辯無礙，能以一妙音遍滿三千界，而不取知味，知味是報法。經云：「諸根通利，智慧明了」也。六根皆智慧，即互用意也。

Third, clarifying the differences among spiritual penetrations: the ghost realm possesses penetrations attained through retribution; humans who are able to ingest medicines also attain penetrations; non-Buddhists also develop penetrations on the basis of the fundamental dhyānas; the devas possess penetrations attained through retribution; the two vehicles, relying on the [eight] liberations, the [eight] bases of mastery, and the [ten] all-pervading bases, cultivate the fourteen transformations to develop and attain spiritual penetrations; the bodhisattvas of the six perfections attain five penetrations through dhyāna, and when sitting at the seat of awakening are able to attain the six penetrations; the bodhisattvas of the shared teaching attain five penetrations through dhyāna, and relying on the wisdom that embodies phenomena, attain the outflow-free penetration; before the stages in the distinctive teaching, they develop the five penetrations relying on dhyāna, and upon ascending the stages, develop the true outflow-free penetration, spontaneously illuminating constantly and not viewing the buddha-lands through dual characteristics. As for the penetrations of the perfect teaching, relying on the present sūtra and the Puxian guan [jing], they take the two sense faculties of nose and tongue to constitute the count of six. The Pusa chutai jing is identical: [knowledge of] others' minds and [recollection of] past lives are subsumed under the mental faculty. However, the text of the sūtra explains the 'penetration of the nose' most exhaustively, adopting its interchangeable function without obstruction. For the tongue faculty, it adopts unobstructedness in the four types of eloquence, being able to fill the three thousand worlds with a single wondrous voice, and does not adopt the knowing of tastes, for knowing tastes is a karmic retribution phenomenon. The sūtra says: 'The faculties are penetrating and keen, and wisdom is clear.' That all six faculties are wisdom is precisely the meaning of their interchangeable function.
