Na kho, Kassapa, pathaviidhaatu saddhamma.m antaradhaapeti, na aapodhaatu
saddhamma.m antaradhaapeti, na tejodhaatu saddhamma.m antaradhaapeti, na
vaayodhaatu saddhamma.m antaradhaapeti. Atha kho idh'eva te uppajjanti
moghapurisaa ye ima.m saddhamma.m antaradhaapenti.

It's from the Saddhammappatiruupaka Sutta (S ii 223-5 = Connected
Discourses, I 681).
