[151] At the moment of the path of Arahantship (arahattamagga), [knowledge is] right view (sammādiṭṭhi) in the sense of seeing … right concentration (sammāsamādhi) in the sense of non-distraction. It emerges from greed for fine-material existence (rūparāga), from greed for immaterial existence (arūparāga), from conceit (māna), from restlessness (uddhacca), from dullness and drowsiness (thīna-middha), from ignorance (avijjā), from the latent tendency to lust for existence (bhavarāgānusaya), from the latent tendency to conceit (mānānusaya), and from the latent tendency to ignorance (avijjānusaya); it emerges from the defilements that follow along with these and from the aggregates (khandha); and it emerges externally from all signs (nimitta). Because of the tranquilizing of that exertion, right concentration arises: this is the fruit of the path.
In the sense of that being known, it is knowledge (ñāṇa); in the sense of understanding, it is wisdom (paññā). Therefore it is said: wisdom in the tranquilizing of exertion is knowledge of fruition (phala).
