Preached to the monks at Icchánangala at the end of the three months' solitude referred to above.
Should anyone ask the monks how the Buddha spent his time during the rainy season, they should reply that he spent it in intense concentration on in-breathing and out-breathing. A life spent by anyone in such concentration would be a life spent according to the Ariyan way and would lead to the destruction of the ásavas (S.v.325f).
