3.289

如是三乘眾生俱越妄想之樊，同適無為之境，無為雖同而乘乘各異，不可以乘乘各異謂無為亦異，又不可以無為既一而一於三乘也。然則我即無為、無為即我，無為豈異？異自我耳。

In the same way, the sentient beings of the three vehicles all leap over the enclosure of false conceptualization and proceed together to the realm of the unconditioned. Although the unconditioned is the same, vehicle and vehicle are each distinct. One cannot, because vehicle and vehicle are each distinct, say that the unconditioned is also distinct; nor can one, because the unconditioned is one, make the three vehicles one. Thus the self is identical to the unconditioned, and the unconditioned is identical to the self. How could the unconditioned be different? The difference comes from ourselves.
