首楞嚴義疏注經 4.577

4.577

因緣所起，自體本無，故云畢竟斷滅。進退推求無我心者，以分別不亡，真覺難顯，但有斷滅，不覺妙常，故云將誰立因求無上覺。

What arises from causes and conditions fundamentally lacks an intrinsic essence; hence it says "ultimate annihilation." Searching back and forth and finding no mind of oneself: because discrimination has not perished, true awareness is difficult to manifest; there is only annihilation and one does not awaken to the wondrously permanent; hence it says "using what can one establish the cause to seek supreme enlightenment."
