Saptaparni cave (P. Sattapa.n.ni-guhaa or Seven leave-cave) is
regarded a place where the first council of the Sa"ngha held. It is
located on the top of the hill Vaibhaara (Vebhaara) in Rajgir. I
visited there few years ago, and doubted the place is possibly not
the actual site of the historical council. Does anyone know any
information regarding how the site is considered the actual site of
the council? Thank you.
Yin-shun has suggested that only SN/SA is originated from the first
council; the other nikaaya/aagamas are not. I am therefore also
interested in the historical site.
