[57] Anyone whose mind (citta), while arising, has passed beyond moment after moment (khaṇaṃ khaṇaṃ), its time gone by — has that one's mind, while ceasing, passed beyond moment after moment, its time gone by?
At the moment of dissolution (bhaṅgakkhaṇa), the mind has passed beyond the moment of arising (uppādakkhaṇa); it has not passed beyond the moment of dissolution. The past mind has both passed beyond the moment of arising and passed beyond the moment of dissolution.
Or conversely: anyone whose mind, while ceasing, has passed beyond moment after moment, its time gone by — has that one's mind, while arising, passed beyond moment after moment, its time gone by?
The past mind.
Anyone whose mind has not, while arising, passed beyond moment after moment, its time not gone by — has that one's mind not, while ceasing, passed beyond moment after moment, its time not gone by?
The mind at the moment of arising, and the future mind.
Or conversely: anyone whose mind has not, while ceasing, passed beyond moment after moment, its time not gone by — has that one's mind not, while arising, passed beyond moment after moment, its time not gone by?
At the moment of dissolution, the mind has not passed beyond the moment of dissolution, yet it is not the case that it has not passed beyond the moment of arising. The mind at the moment of arising, and the future mind, have both not passed beyond the moment of dissolution and not passed beyond the moment of arising.
