At Anomadassi's time, Gotama Buddha was a Biru (English: Ogre, Burmese:ဘီလူး) leader. After listening to the teachings of the Buddha, he invited him and his disciples to his place. He fed them and filled their needs for seven days. After a week of donation, Anomadassi said:

"This ogre will become a Buddha named Gotama in the Bhadda kalpa that will appear after many aeons."

The incarnation of Gotama Buddha, having his wish granted, decided to practice Pāramitā
