Five perceptions that ripen in freedom are taught at DN 33:2.1.139, but apart from that we do not encounter this idea in the discourses. | In SN 18.1–5, Rāhula requests a teaching so he can go on retreat. The teachings given there can be compared with the parallel, which says the Buddha first told Rāhula to teach the five aggregates, the six sense-spheres, and conditionality, and then to go on retreat and meditate on the same teachings (SA 200 at T ii 51a23). Only then did the Buddha consider him ready.

The sitting cloth was a standard requisite of monastics (Bu Pc 89). Regularly featured in the texts of the Sarvāstivāda schools, it is rarely mentioned in the Pali suttas (but see DN 16:3.1.3).

The presence of thousands of deities, which is unique to this discourse, is not mentioned in the Chinese parallel, and is obviously a later addition.
