Ananda visits a settlement of nuns at Sávatthi and is told that the nuns who have cultivated the four satipatthánas have attained to greater excellence of comprehension than before. Ananda says that is how it should be. Later, he visits the Buddha and reports to him the incident. The Buddha tells him how to develop the satipatthánas and of the advantages resulting there from.
The sutta ends with an exhortation to earnestness and diligence. There are plenty of places suitable for meditation, one should not therefore be remiss with regard to this. S.v.154f.
