經律異相 13.14

13.14

即起三三昧。如一入涅槃以三山覆身。如子入母腹。而自不失壞。二若阿闍世王來。先約相見。來者山應當開。阿闍世若不見我。當吐熱血死。三阿難來山開。彌勒與九十六千萬弟子來此。取迦葉身以示眷屬。令悉學我持戒功德（出阿育王經第七卷）。

He then arose in three samādhis: First, as when entering nirvāṇa, the three mountains cover his body as a child enters its mother's womb, remaining undamaged. Second, if King Ajātaśatru comes, having prearranged to see him, the mountain should open when he comes; if Ajātaśatru does not see me, he will vomit hot blood and die. Third, when Ānanda comes, the mountain opens; and when Maitreya comes here with ninety-six thousand million disciples, he will take Kāśyapa's body to show his assembly, causing them all to emulate my merits of upholding the precepts (Extracted from the Aśokāvadāna, Fascicle 7).
