首楞嚴義疏注經 5.64

5.64

分別不生，前後際斷，真尚不辨，妄何所立？是故性真常中求於去來、迷悟、死生了無所得，斯則一相平等，迷悟都亡，生死涅槃猶如昨夢。故肇公云：「夫不存無以觀法者，可謂見法實相矣。」

When discrimination does not arise, the boundaries of before and after are severed; when even the true is not discerned, where can the false be established? Therefore, within the true and constant nature, seeking coming and going, delusion and awakening, death and life, absolutely nothing can be found. This, then, is the single characteristic of equality: delusion and awakening are both eliminated, and saṃsāra and nirvāṇa are like yesterday's dream. Thus Master Zhao said: "One who observes dharmas without maintaining non-existence can be said to see the true reality of dharmas."
