Without a link, it is very difficult to check the translation of a quote, especially suttas from the Anguttara Nikaya, because there seems to be no numbering convention there to follow. Is this sutta from volume 1 book 4, but there is no 170th sutta anywhere in the AN; however, there might be a 170th line, so is it volume 4 line 170? The reason why I wish to check this translation is in most cases where a translated sutta states the idea of vipassana verses jhana, in most cases we find the translation was forced, because the term vipassana ussually does not even appear in the sutta.
