一實相者，謂真實之理，無二無別，離諸虛妄之相也。
The state of bhūtatathatā, above all differentiation, immutable; it implies the Buddha-nature, or the immateriality and unity of all things; 真如之理無二無別, 離諸虛妄之相; it is undivided unity apart from all phenomena.
一一實相 指真實無二之理，即真如、法性；以其無二無別，離諸虛妄，故稱一實相。往生要集卷中（大八四‧六六下）：「諸眾生妄想夢未覺，不解一實相，生是非想，輪回五道。」p123
一切事物的真相或真理。
