1.99

時善賢妃欲立長壽。白王擯遣四子出國。至雪山北自立城居。不數年間欝為強國（本行經。往靈山建國。城號迦毘羅。其王名別成。遠近欽服）父王悔憶遣使往召四子辭過不還。父王三歎之曰。我子釋迦（此云能仁本行經）到雪山邊住直樹林中。故名為釋迦（此云直林長阿含經）近雪山北舍夷林築城營舍。因名舍夷國（五分律）。

At that time, Queen Bhadrā, wishing to establish Dīrghāyus, requested the king to banish the four sons from the country. Reaching the north of the Snow Mountains (Himālaya), they established a city and dwelt there, and in not many years it flourished into a powerful state. (The *Benxing jing* says they went to the sacred mountains to found a state; the city was named Kapilavastu, and its king was named Biecheng, revered and obeyed near and far.) Their royal father, regretting and longing for them, sent an envoy to summon them, but the four sons declined on account of their fault and did not return. The royal father sighed three times in praise of them, saying: "My sons are Śākyas (translated here as 'able and benevolent'; *Benxing jing*)." Because they arrived at the edge of the Snow Mountains and dwelt in a grove of straight trees (śāka), they were named Śākya (translated here as 'straight grove'; *Dīrgha-āgama*). Because they built a city and constructed residences near the Sākiya grove north of the Snow Mountains, it was named the Sākiya State (*Pañcavargika-vinaya*).
