[52] For whomever the mind (citta) is ceasing, has that person's mind arisen?
Yes.
Or rather, for whomever the mind has arisen, is that person's mind ceasing?
At the moment of the mind's arising (uppādakkhaṇa), the mind of those [persons] has arisen, but their mind is not ceasing; at the moment of the mind's dissolution (bhaṅgakkhaṇa), their mind has both arisen and is ceasing.
For whomever the mind is not ceasing, has that person's mind not arisen?
At the moment of the mind's arising, the mind of those [persons] is not ceasing, yet it is not that their mind has not arisen. For those who have attained cessation (nirodhasamāpanna) and for non-percipient beings (asaññasattā), their mind both is not ceasing and has not arisen.
Or rather, for whomever the mind has not arisen, is that person's mind not ceasing?
Yes.
