Reflectinga little:
At the time of the Buddha, Brah Shiva gained the path, dwelling in Tāvatiṁsa Deva-Loka. At the end of his Existance, seeing the decay of the Sasana, 500 years after the Buddhas Parinibbana, Shiva asked the King of Devas, Sakka, to return into the Human Realm. Informing of the dangers, the King gave leave.
As a Brahman Son, Named Koṇḍañño under the tribe Kambos who at this time wandered toward South-East Asia, he lead an ascetic life. One Day reminded by a Deva in dream, he headed toward the land of the Naga-tribe, the mountain folk, where a met "again" Naga Soma (Uma) and not only founded the Kingdom of the Khema, but also established them in the Dhamma of the Buddha. Having fallen from here, he dwelled another life-time in the Sugati realms, gained there the fruit of once-returner. Again, at the end of this lifespann, he asked to return, seeing the decay of the Dhamma in his former kingdom, 2500 years after the Buddhas Parinibbana.
Again he would become in Western Land as Son of poor Brahmans, again one day a "Deva" whould have remind him, heading toward the holly life of no more return, after the last Sanghayana.
