首楞嚴義疏注經 1.61

1.61

結悲化無盡也。拔令脫苦，濟使得樂。佛滅度後，故曰未來。煩惱與業染污繫縛，喻之塵累。皆令清淨自在無礙，故稱越也。

This concludes [the explanation of] compassion and teaching being without end. Pulling them out causes them to be free from suffering; rescuing them enables them to attain joy. Since it is after the Buddha's extinction (parinirvāṇa), it says "the future." Afflictions and karma are defiling and binding, and are compared to the entanglements of dust. Causing all to become pure, sovereign, and unimpeded is therefore called "surpassing."
