首楞嚴義疏注經 10.116

10.116

見前三陰已滅，當知行陰亦應還滅，即計死後斷滅，總名無相。

Seeing that the preceding three aggregates are already eliminated, he understands that the aggregate of formations should also be eliminated in turn, and immediately calculates annihilation after death, collectively termed 'having no characteristics'.
