Preached to the monks at the Gotamakacetiya. The Buddha declares that his proclamation of a Dhamma is with full comprehension, with casual connection (sanidānam), and accompanied by wonders. His instructions are with reason (A.i.276f).
It is said that at this pronouncement the thousand fold universe trembled (Also DA.i.130; J.ii.259).
The Majjhima Commentary (i.49) states that the Sutta was preached to the monks mentioned in the Mūlapariyāya Sutta, and that, at the end, they became arahants.
