So if that Arahant (or the lower level of attainment) is the latter then he or she had the jahna. Jhana is not the requirement for arahantship. The word sammasamadhi=right concentration, vipassana that leads to arahantship is also sammasamadhi by itself (vipassana has no need to have right concentration to the level that gain one of the four jahna).
I understand what you're saying. That's what I was taught to believe many years ago.
As I now understand, the concept of Arahant without jhana is acceptable if we are referring to the kind of jhana Visuddhimagga talks about, which is not the same as the 4 jhanas in the Suttas. If you can find any reference in the Suttas on Arahants without jhanas (the Sutta type of course), please let me know.
