佛說觀普賢菩薩行法經 1.37

1.37

「淨眼根已，復更誦讀大乘經典，晝夜六時胡跪懺悔而作是言：『我今云何但見釋迦牟尼佛分身諸佛，不見多寶佛塔、全身舍利？多寶佛塔恒在不滅，我濁惡眼是故不見。』作是語已，復更懺悔。過七日已，多寶佛塔從地涌出，釋迦牟尼佛即以右手開其塔戶。見多寶佛入普現色身三昧，一一毛孔流出恒河沙微塵數光明，一一光明有百千萬億化佛。

“Having purified the eye faculty, he again recites and reads the Mahāyāna scriptures, and throughout the six periods of the day and night kneels with his right knee on the ground to repent, speaking these words: ‘Why is it that I now only see Śākyamuni Buddha and the emanation Buddhas, but do not see the stūpa of Prabhūtaratna Buddha and the whole-body relics? The stūpa of Prabhūtaratna Buddha constantly exists and is never annihilated, yet because of my turbid and evil eyes I do not see it.’ Having spoken these words, he repents further. When seven days have passed, the stūpa of Prabhūtaratna Buddha wells up from the earth, and Śākyamuni Buddha immediately opens the door of the stūpa with his right hand. He sees Prabhūtaratna Buddha entering the samādhi of universally manifesting form bodies, from each and every pore pouring forth light as numerous as the dust motes of the Ganges sands, and in each and every ray of light are hundreds of thousands of myriads of koṭis of transformation Buddhas.
