Rahogatasutta untranslated

Rahogatasutta 01. While in solitude a monk thinks of the three kinds of feelings, and, visiting the Buddha, questions him. The Buddha tells him that the statement, “Whatsoever is experienced is joined with dukkha” is made concerning the impermanence of compounded things. The ceasing of activities is gradual, so is their mastery. SN.iv.216f.

Rahogatasuttā 02. Two Suttas. Moggallāna visits Anuruddha, as the latter is meditating in solitude in Jetavana, and asks for details as to how a monk should practice the four satipaṭṭhānas. Anuruddha explains. SN.v.294ff.
