菩薩從兜術天降神母胎說廣普經 4.37

4.37

爾時，有菩薩名曰無盡意，即從坐起偏露右臂右膝著地，叉手合掌前白佛言：「未曾聞如來說法，此四種人得成佛者，今日乃能開演大義。」即重白佛：「捨身、受身、即身成佛耶？」

At that time, there was a bodhisattva named Akṣayamati, who immediately rose from his seat, bared his right shoulder, touched his right knee to the ground, joined his palms with folded hands, stepped forward, and said to the Buddha: "Never before have we heard the Tathāgata preach that these four kinds of persons can attain Buddhahood; only today can you unfold this great meaning." He then asked the Buddha again: "Is it by relinquishing the body, receiving a body, or in this very body that they attain Buddhahood?"
