Mentioned as having stayed with Mahā Moggallāna on Gijjhakūṭa. Once, when they were going down to Rājagaha for alms, Lakkhaṇa noticed that at a certain spot Moggallāna smiled; on asking him why, he was told to wait till they saw the Buddha. When the question was repeated in the Buddha’s presence, Moggallāna said that he had smiled on seeing various Petas with gruesome forms flying through the air. From the text it would appear that these visions were seen again on several occasions. SN.ii.254 Vin.iii.104ff.
When Moggallāna related his vision, some of the monks blamed him for claiming superhuman powers, but the Buddha declared him free from blame. Vin.iii.105
