I also wonder about how early Buddhism differs, if at all, from Theravada regarding the notion of the Buddha sasana (dispensation or teaching).
There seems to be a belief in Myanmar (maybe elsewhere?) that the sasana occurs in cycles, that in 500 year periods from the time of the Buddha, the dispensation will decline starting first with fewer arahants and the availability of wisdom practices; then the occurance of beings who have attained the 8 jhana concentration practices and can teach them; then the preponderance of people keeping their sila precepts; then the decline of Dana culture; then the availability of the scriptures and pariyatti until the 2,500 year mark, when the sasana will experience a resurgence and the teachings will spread around the world, growing until the arising of Mateyya Buddha. In some circles in Myanmar, the 2500th year is considered around the time of 1954-1956, when the Sixth Synod Council convened.
For 30 years I was involved with a tradition whose lay teacher leader insinuated that he was the harbinger of the second cycle of this resurgent cycle of the Buddha sasana by virtue of the fact that he started meditating under his Dhamma teacher at that time and then in the late sixties, early seventies was responsible for popularizing Dhamma teachings in India and, via international students, subsequently around the world.
My first question is, how widespread is this notion of resurgent cycles of the sasana in Myanmar among other traditions in that country and is it shared by other Theravada countries like Thailand, Sri Lanka, Cambodia etc.?
I’ve heard, since leaving this tradition, that at least one other Myanmar tradition believes that the sasana is in decline and is continuing that decline by virtue of how few fully attained arahants, anagamis, sakadagamis and sotapannas there are present now in the world.
That the commercialization, secularization and even popularization of the teachings as well as proliferation of 10-day retreats compromised for modern life is a demonstration of this decline.
How does this notion of sasana cycles square with early Buddhism? Would this be a useful topic/clarification to include in the checklist?
