Iti ajjhattaṃ vā dhammesu dhammānupassī viharati, bahiddhā vā dhammesu dhammānupassī viharati, ajjhattabahiddhā vā dhammesu dhammānupassī viharati, samudayadhammānupassī vā dhammesu viharati, vayadhammānupassī vā dhammesu viharati, samudayavayadhammānupassī vā dhammesu viharati, ‘atthi dhammā’ ti vā panassa sati paccupaṭṭhitā hoti.

Thus he dwells observing mental contents in mental contents internally, or he dwells observing mental contents in mental contents externally, or he dwells observing mental contents in mental contents both internally and externally. Thus he dwells observing the phenomenon of arising in the mental contents, thus he dwells observing the phenomenon of passing away in the mental contents, thus he dwells observing the phenomenon of arising and passing away in the mental contents. Now his awareness is established: "These are mental contents!" Thus he develops his awareness to such an extent that there is mere understanding along with mere awareness. In this way he dwells detached, without clinging towards anything in the world [of mind and matter]. This is how, monks, a monk dwells observing mental contents in mental contents as regards the six internal and external sense spheres.
