首楞嚴義疏注經 3.304

3.304

求開示也。方便安立，說有四大因緣和合成諸變化。第一義中諸法不生，今則無滅，生滅去來本如來藏。今以世諦疑第一義，故有斯難。

This is seeking instruction. By expedient establishment, it was taught that the causes and conditions of the four great elements combine to accomplish all transformations. In the supreme truth, all dharmas are unarisen, and now they do not cease; arising, ceasing, coming, and going are originally the tathāgatagarbha. Now, using worldly truth to doubt the supreme truth, this objection is raised.
