Personalities of the Buddhist Suttas
Dictionary of Pali Proper Names: Mentioned as having stayed with Mahaa Moggalaana on Gijjhakuu.ta. Once, when they were going down to Raajagaha for alms, Lakkha.na noticed that at a certain spot Moggallaana 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, Moggallaana 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.
The Commentary explains that Lakkha.na was one of the thousand Ja.tilas ordained by the Buddha (when he converted the Tebhaatika Ja.tilas). [for the conversion of the three famous Kassapas see Vin. Texts i, 132-5] He attained arahantship at the conclusion of the preaching of the Aadittapariyaayadesanaa. [SN 4.35.28] He was called Lakkha.na because of his marvellous personality, "like unto Brahmaa's" It adds further that Lakkha.na's failure to see the Petas was not because he lacked the divine eye but because he was not giving attention as a clairvoyant must. It is said that when Moggallaana related his vision, some of the monks blamed him for claiming superhuman powers, but the Buddha declared him free from blame.
