肇論新疏 3.311

3.311

如是三乘眾生，俱濟緣起之津、同鑑四諦之的，絕偽即真同升無為，然其所乘不一者，亦以智力不同故也。

Thus sentient beings of the three vehicles together cross the ford of dependent origination, together behold the target of the four noble truths, and abandoning falsity to approach truth, together ascend to the unconditioned; yet that what they ride upon is not one is also because their powers of wisdom are not the same.
