what does “ad delo yada” mean according to your rabbeim?
Rabbi Avigdor Miller, tz’l, states that ad dlo yada means ad v’lo clal, in other words up until but not including. I realize this is not the usual understanding, nevertheless this is what he holds. I do not know his source.
He holds in other words this point is not to be reached, and anything less is the maximum and not the shiur.
I did not hear him express a minimum but he states that the purpose of drinking is to stimulate your Simcha WITHOUT losing your seichel.
