Dhammapada Verse 79
The Story of Thera Mahakappina
Mahakappina was king of Kukkutavati. He had a queen named Anoja; he also had one thousand ministers to help him rule the country. One day, the king accompanied by those one thousand ministers, was out in the park. There, they met some merchants from Savatthi. On learning about the Buddha, the Dhamma, and the Samgha from these merchants the king and his ministers immediately set out for Savatthi.
On that day, when the Buddha surveyed the world with his supernormal power, he saw in his vision, Mahakappina and his ministers coming towards Savatthi. He also knew that they were due for arahatship. The Buddha went to a place one hundred and twenty yojanas away from Savatthi to meet them. There, he waited for them under a banyan tree on the bank of the river Candabhaga. King Mahakappina and his ministers came to the place where the Buddha was waiting for them. When they saw the Buddha, with six-coloured rays radiating from his body, they approached the Buddha and paid homage to him. The Buddha then delivered a discourse to them. After listening to the discourse the king and all his ministers attained Sotapatti Fruition, and they asked the Buddha to permit them to join the Order. The Buddha, reflecting on their past and finding that they had made offerings of yellow robes in a past existence, said to them, "Ehi bhikkhu", and they all became bhikkhus.
