"Every instance of ‘contact’ is immediately perceived as either pleasure, pain or neutral.

The person (pudgala, P. puggala)—insofar as ‘person’ is merely a designatory label (prajñapti) for the karmic stream (santāna)

produced by and producing pain and pleasure—develops and is conditioned by the repeated experiences of these positive and negative reinforcements,

viz. enjoyment and hurt, reward and punishment, etc."
