Cubibobi mentions LISTENING to a desana by an Ariya. This reminds me that Lal said he would say whether listening is a requirement in attaining the Sotapanna
Stage when he finds that information. Perhaps Lal has since and I missed it?
At any rate, yes, Cubibobi, for me it has worked like that. Those four. But I included vimansa (analysis, investigation), mainly as to whether anything in particular is consistent with the rest of Dhamma.
May you progress on the Path.
