Angulimala
It was in the 20th year that the Buddha converted the notorious murderer Angulimala. Ahimsaka - Innocent - was his original name. He belonged to a distinguished family, and was the most illustrious and favorite pupil of his renowned teacher.
Unfortunately his associates grew jealous of him, concocted a false story, and succeeded in poisoning the teacher against him. The enraged teacher, without any investigation, contrived to put an end to his life by ordering him to fetch a thousand fingers as a present. In obedience to the teacher, though with great reluctance, he repaired to the forest and started killing people to collect fingers for the necessary offering. Later he wore a garland of these fingers to ascertain the number - hence the name Angulimala.
When he had collected 999 fingers, so the book state and was ready to complete the number, the Buddha appeared on the scene. Angulimala made a vain attempt to kill the Buddha, but was eventually converted to the noble Dhamma and was admitted into the Order. One day as he went on his alms-round he saw a woman in travail. Moved by compassion he reported this pathetic case to the Buddha who then taught the Angulimala Paritta which runs as follows:-
"Sister, since I was born in the Ariyan clan, I know not that I consciously destroyed the life of any living being."
"By this truth may you be whole, and may your child be whole!"
He studied this Paritta, and going to the presence of the suffering sister sat on a seat separated from her by a screen, and made this Act of Truth. Instantly she was delivered of the child with great ease. The efficacy of this Paritta persists to this day.
In due course Venerable Angulimala attained Arahantship.
The remaining twenty-five years were spent in Savatthi at the Jetavana Monastery, built by Anathapindika, the millionaire, and at Pubbarama, built by Visakha, the chief benefactress of the Buddha.
