In De Troyes' narrative, after Perceval sets out for the grail again, he wonders about for five years, forgetting his purpose and his devotion to God. One day, he is reminded by some ladies that it is Good Friday and that he should be in church:

Perceval set out on the path, sighing deep within his heart because he felt he had sinned against God and was very sorry for it. Weeping, he went through the thicket, and when he came to the hermitage, he dismounted and removed his armor. He tied his horse to a hornbeam and entered the hermit's cell. [...] And Perceval, who was very much afraid that he had sinned against Almighty God, took the hermit by the foot, bowed before him and with hands clasped begged him to give him absolution. (459)

The hermit reveals that he is Perceval's uncle and that Perceval's sin consists of causing his mother's death, for on learning that he became a knight, she died of grief. The hermit encourages Perceval to be penitent and guides him in his penance:

"Now I would wish you to remain here with me for two full days, and in penitence to take only such nourishment as I do."

[...] So he remained and heard the service and his heart filled with joy; after the service he worshipped the Cross and wept for his sins. And that night for supper he had what the hermit liked, though there were only herbs - chervil, lettuce, and watercress - and barley and oat bread, and clear spring water. (460-1)
