2.271

[The text states:] "The fifth is named continuing consciousness, because it is conjoined with thought without interruption; because it sustains the good and evil karma of immeasurable past lifetimes, etc., so that it is not lost; because it can further mature the pleasant and painful retributions of the present and future without error or discrepancy; and because it can make what has already passed in the present suddenly come to mind, and unconsciously harbor delusive concerns about future matters."
