又彌勒所問本願經云。佛言阿難我本求道時。勤苦無數。過去世時有王太子。號曰寶華。端正姝好。從園觀出。道見一人身患病癩。見問病人。以何等藥療卿病。癩者答曰。得王身髓血等以塗我身。其病乃愈。太子聞已。即自破身骨髓血等。以與病者。至心施與意無悔恨。其王太子者即我身是。四大海水尚可升量。我身骨髓血等不可稱數。求正覺故。

Furthermore, the Maitreyaparipṛcchā-dharmaparyāya states: The Buddha told Ānanda: "When I originally sought the Way, my toil and suffering were countless. In a past age, there was a king's prince named Ratnapuṣpa, upright and handsome. Coming out of a pleasure garden, he saw a man on the road suffering from leprosy. Seeing him, he asked the sick man: 'What kind of medicine will cure your illness?' The leper answered: 'If I obtain the marrow and blood of a king's body to smear on myself, the illness will be cured.' Having heard this, the prince immediately broke open his own body, taking bone marrow, blood, and the like, to give to the sick man. He gave with a sincere mind, without regret. That king's prince was myself. The waters of the four great oceans can still be measured by pints, but the bone marrow and blood of my bodies cannot be counted, all for the sake of seeking saṃbodhi."
