妙法蓮華經玄義 7.187

7.187

復次，迹中約實施權，意在於實，而實意難測。何者？化城是權，而人作實解，是不識權，亦不知實。若廢權顯實，意在於權，權則易測，何者？既知化城一事是佛權施，則遍達恒沙佛法，遠通久劫方便。故《華嚴》中明，為阿鞞跋致多明事數，即其義也。若開權顯實者，達事法已，權意即息，亦不離權遠求於實。權即是實，無復別權，故言開權顯實也。

Furthermore, within the traces, applying the provisional based on the real has its intention in the real, but the intention in the real is difficult to fathom. Why? The conjured city is provisional, but people understand it as real; this is not recognizing the provisional and also not knowing the real. If one abolishes the provisional and reveals the real, the intention is in the provisional, and the provisional is then easy to fathom. Why? Since one knows that the single matter of the conjured city was the Buddha's provisional deployment, one then comprehensively fathoms the Buddha-dharmas [as numerous as] the sands of the Ganges, and reaches far back to the expedients of long eons ago. Therefore the Avataṃsaka explains that for an avaivartika, many enumerations of things are clarified—this is precisely that meaning. If one opens the provisional and reveals the real, having penetrated phenomenal dharmas, the intent of the provisional then ceases, nor does one seek the real far away apart from the provisional. The provisional is none other than the real, and there is no separate provisional besides; therefore it is said to open the provisional and reveal the real.
