Repeated recitation does not exist solely to discover new information. Even when the meaning is familiar, recitation brings it back to attention and reconnects conduct with its demands. Thus recurrence in recitation and recurrence in subject matter serve related purposes.
Treating the first successful understanding of a text as the end of its benefit would overlook reminders, moral formation, and the renewal of intention. Ordinary occupations can distance a person from a truth already known; presenting it again provides an independent benefit.
The purpose of reminder: to turn stored information back into active guidance.
