佛說觀佛三昧海經 3.53

3.53

At that time, hearing these words of the Buddha, the monks each reproached themselves, bared their right shoulders, joined their palms toward the Buddha, and spoke these words: "In past lives countless kalpas ago, we held wrong views, doubted our teacher, and received the alms of the faithful in vain. Due to these causes and conditions, we fell into the hells. Although we have now emerged, for immeasurable lifetimes we did not see the Buddhas but merely heard their names. Now we see the Bhagavat's body as the color of red earth, exactly five feet in height."
