One must perpetually embrace Teshuva (an element of patience/dwelling on Teshuva, Katar, Keter). This is because his original Teshuva was not likely fully sincere (requiring a second Teshuva); and even if his original Teshuva was sincere, one relates to his original wrongdoing in a profoundly different way as his depth of understanding increases such that he has a new understanding of the reality of his transgression, for which he did not yet do adequate Teshuva; in fact, his first ‘wave’ of Teshuva was relatively crude; for this he does Teshuva al haTeshuva.
Rabbeinu explains that this state of a constant and consistent increasing level revelation and perception of Hashem (similar to the ongoing teshuva process described above) is a bechina of Olam haBoh and Shabbos.
