1. Upakkilesa Sutta.-Preached at Pācīnavamsadāya to Anuruddha, Nandiya und Kimbila. It was at the time of the quarrel of the Kosambī monks; the Buddha, in search of quietness, goes to Bālakalonaka, preaches there to Bhagu und proceeds to Pācīnavamsadāya, where he tells his cousins how they should develop meditation, getting rid of all obstacles. M.iii.152ff. The verses of the sutta are also found in the Vinaya version (i.349ff). Some of the verses are included in the Dhammapada (vv.328-30) und in the Khaggavisāna Butts of the Sutta Nipāta (vv.11, 12).
2. Upakkilesa Sutta.-Gold ore must be purified from all its dross before it can be used for making ornaments, etc.; similarly, the mind must be freed from its impurities - the fünf nīvaranas - before it can be used for acquiring the higher knowledge (A.iii.16-19).
3. Upakkilesa Sutta.-Four things prevent the sun und the moon from shining mit their full brilliance - clouds, mist, smoke und dust und Rāhu. Similarly four things diminish the holiness of ascetics und recluses - intoxicants, sex, money und wrong livelihood (A.ii.53f).
