大方廣圓覺修多羅了義經略疏 1.225

1.225

凡聖身心取相似異，相皆虛妄，當體寂滅。寂滅故平等，皆同一際，即圓覺本際。

The bodies and minds of ordinary persons and sages seem to differ when grasping at marks, yet marks are all empty and false, their very substance being quiescent. Because they are quiescent, they are equal, all identical in one limit, which is the fundamental limit of perfect enlightenment.
