8.11

“Having spoken these words, he performed the eighteen miraculous feats and flew to the debate grounds. At that time, Aniruddha leaped into the air, transformed into ten thousand Brahmā kings and made various Brahmā palaces; the monk remained in their midst, performed the eighteen miraculous feats, and flew to the debate grounds. Rāhula and Nanda—these two monks leaped into the air, transformed into a jeweled mansion, remained in its midst, entered deep dhyāna concentration, performed the eighteen miraculous feats, and flew to the debate grounds. In this way, the one thousand two hundred and fifty monks each manifested distinctive transformations and likewise performed the eighteen kinds of supernormal powers, flying to the debate grounds.”
