The content describes about the story of the Bodhisattva being born as Usuphkumman. The story is that a cow named Usuparat living near the hermitage of Hermit Thukula in the Himalaya gave birth of a human baby. Later her son was given a name as Usuphakumman by the hermit. Then the cow offered her son to the hermit as his disciple and went away. When Usuphakumman was grown up, he asked the hermit for his mother. Then he entered the forest for seeking his mother.
