Note 6 — Chapter XX · KOŚALA AND ŚRÂVASTÎ. THE JETAVANA VIHÂRA AND OTHER MEMORIALS AND LEGENDS OF BUDDHA. SYMPATHY OF THE MONKS WITH THE PILGRIMS.
James Legge translation
The Aṅgulimâlya were a sect or set of Śivaitic fanatics, who made assassination a religious act. The one of them here mentioned had joined them by the force of circumstances. Being converted by Buddha, he became a monk; but when it is said in the text that he ‘got the Tâo,’ or doctrine, I think that expression implies more than his conversion, and is equivalent to his becoming an Arhat. His name in Pâli is Aṅgulimâla. That he did become an Arhat is clear from his autobiographical poem in the ‘Songs of the Theras.’
