[Jittananto]

What I mean is that the sutta says that Venerable Arahant Sāriputta practiced jhānas for a fortnight. At the end of this fortnight, he reached Nirodha Samapatti. That means he became an arahant. However, in the Dīghanakhautta, he became an arahant by reflecting on the discourse of Lord Buddha. Sutta’s central statement is a contradiction because it says that he realized nirodha samapatti between the time he became sotāpanna and the time he became an arahant. The logical explanation is that he practiced jhānas and nirodha samapatti after becoming an arahant.
