首楞嚴義疏注經 5.194

5.194

塵無自性，纔生即滅。體是幻有，性相本空。水無所因，安然不動。三俱無得，孰為浴事？無始妄習頓然銷落，乃至今時得成無學。

Dust has no intrinsic nature: as soon as it arises, it perishes. The body is an illusory existence: its nature and characteristics are originally empty. Water has no cause: it is peaceful and unmoving. All three being ungraspable, what constitutes the act of bathing? Beginningless delusional habituations abruptly dissolved away, up until the present when we have attained [the stage] beyond study.
