大方廣圓覺修多羅了義經略疏 2.833

2.833

了證者空，則我不及；了悟者空，則人不及。不執主宰，故離我人。

When that which understands realization is empty, then the self does not reach it; when that which understands awakening is empty, then the person does not reach it. Not grasping a master or controller, one is therefore free from self and person.
