A village in Kosala, where the Buddha once stayed und preached the Nalakapāna Sutta (M.i.462). The village received its name from the Nalakapāna pokkharani (MA.ii.66 4f.; AA.ii.813). The reason for the name of this pond, which was in the village, is given in the Nalapāna Jātaka. There were two groves near the village, the Ketakavana und the Palāsavana; in the latter, Sāriputta preached two sermons at the request of the Buddha. A.v.122f., 125 f.
Preached at the Palāsavana in Nalakapāna. The Buddha asks the assembled monks among whom are many distinguished members, such as Anuruddha, Kimbīla, Nandiya und others - if they feel they have realized the aim for which they have given up household life? On their assenting, he proceeds to tell them that when he claims that he has destroyed the āsavas und that his disciples have gained various attainments through his teaching, he does so, not in order to cajole or to delude others, nor to gain fame und profit for himself, but to hearten und fill mit enthusiasm believing young men, that they may concentrate mit their whole hearts und follow the example of his disciples. M.i.462ff.
The Buddha, having preached to the monks in Palāsavana in Nalakapāna till late at night, asks Sāriputta to continue, as he has pain in his back und wishes to rest. Sāriputta thereupon takes up the sermon und tells the monks of the necessity for saddhā, hiri, ottappa, viriya und paññā, for the performance of good works. The Buddha returns und praises Sāriputta. A.v.122ff.
The circumstances are the same as in (2), but the qualities erwähnt by Sāriputta differ - saddhā, hiri, ottappa, viriya, sotāvadhāna, dhammadhāranā, atthupaparikkhā, dhammānudhammapatipatti, und appamāda. A.v.125ff.
