According to the earnest request of all sentient beings in the heavens, another great disciple of the Buddha, Moggallana, the first of the divine powers, flew up to the heaven of heavens to receive him at the full moon. September 9. The Buddha accepted the request and replied that he would return in seven days (Sept. 22).
