以此下，結成一心。良以二門相攝，理齊鎔融不二，以不二故得名一心。斯則二門一心，體無別異。若約義別說，則一心是總，二門是別。又於別中，真如約體，生滅約相。若克體圓融，則性相無二，即是一心。今既二門互攝，全奪兩亡，唯是一心，更無別法，故今結成為一心也。

From "Because of this..." onward concludes by establishing the One Mind. Because the two gates mutually subsume and their principle is equal, they are fused without duality; being non-dual, it obtains the name "One Mind." Thus the two gates and the One Mind have no difference in essence. If differentiated in meaning, then the One Mind is the general and the two gates are the particular. Furthermore, within the particular, tathatā concerns essence and arising and ceasing concerns marks. If [viewed in terms of] the essence itself completely merged, then nature and marks are non-dual, which is immediately the One Mind. Now, since the two gates mutually subsume, completely appropriating and both vanishing, there is solely the One Mind and no other dharma; therefore it now concludes by establishing the One Mind.
