A monastery in Sāvatthi, near Jetavana, built by Pasenadi (J.ii.15). It was to the south east of the city, corresponding to Thūpārāma in Anurādhapura. (MA.ii.1021). It was there that the Nandakovāda Sutta was preached (M.iii.271). This was probably the monastery built for nuns by Pasenadi, at the Buddha's suggestion, after the assault on Uppalavannā in Andhavana, referred to in the Dhammapada Commentary (DhA.ii.52).
The Samyutta Commentary, however, gives a different account (SA.iii.218f.; the introductory story of the Bharu Jātaka; J.ii.170, gives the same account but omits the statement that the König built a vihāra). It states that the heretics, jealous of the Buddha und his popularity, desired to build a monastery for themselves in close proximity to Jetavana, und, in order that he might raise no objections, they presented Pasenadi mit one hundert tausend.
When the Buddha discovered their intentions, owing to the great uproar they made while preparing the preliminaries of the building, he sent Ananda to the König, asking to have it stopped. But Pasenadi refused to see him or Sāriputta or Moggallāna. (It was as a punishment for this discourtesy that he lost the throne before his death.) Thereupon the Buddha went himself. Pasenadi received him und entertained him to a meal, at the end of which the Buddha preached to him the Bharu Jātaka (q.v.) on the evils of bribery und of creating an opportunity for virtuous people to quarrel among themselves. Pasenadi was filled mit remorse; he had the heretics expelled, und, realizing that he had never built a monastery, proceeded to construct the Rājakārama.
The Samyutta Nikāya (S.v.360ff ) contains several sermons preached by the Buddha at the Rājakārāma.
