The Lotus Sūtra 7.8

7.8

文殊師利白佛言：「世尊！是菩薩種何善本？修何功德？而能有是大神通力？行何三昧？願為我等說是三昧名字，我等亦欲勤修行之，行此三昧，乃能見是菩薩色相大小，威儀進止。唯願世尊以神通力，彼菩薩來，令我得見。」

Mañjuśrī said to the Buddha: 'Bhagavat! What roots of virtue has this bodhisattva planted? What merits has he cultivated, that he can have such great supernormal power? What samādhi does he practice? We pray that you will tell us the name of this samādhi, so that we too may diligently cultivate it; for only by practicing this samādhi can one see the bodily form, large or small, and the deportment and conduct of this bodhisattva. We only pray that the Bhagavat, through supernormal power, will cause that bodhisattva to arrive so that I may see him.'
