[1] At the age of 30, Iyasus Mo'a travelled to the monastery of Debre Damo during the abbacy of Abba Yohannis where he was made a monk, and was given arduous tasks by the abbot.

After seven years, he left Debra Damo and came to live with a eremetic community around the eighth-century church of Istanafanos at Lake Hayq, and organized this group into a monastery with rules and a school.

His mother, upon hearing such prediction, brought him to Istifanos Monastery in Lake Hayq and begged the priests there to hide her son and save him from being killed.

Iyasus Mo'a protected and educated the boy, and in return, Emperor Yekuno Amlak built the structure to house his community.

Later hagiographies state that Yekuno Amlak was helped by Tekle Haymanot, but the critical researches of Carlo Conti Rossini suggest that the Gadla Iyasus Mo'a is closer to the correct version of events.
