Even though it it seems clear that the Musar movement (to learns the mediaeval books on Ethics)as thought of by Rav Israel Salanter is not all that possible, still I think that it could be given a new beginning with an extra emphasis on this in the great Litvak yeshivot. I suggest instead of the very short periods, 20 minutes before minha (afternoon prayer) and 15 minutes before arvit (evening prayer), why not go back to the way things were when Musar was first introduced in the Litvak yeshivot, two forty minute sessions?
Still i must add here, in the Torah there is a commandment not to add or subtract from the commandments. So the religious world which is constantly adding and subtracting can not be considered to be keeping the Torah even in the most farfetched sense. But they get away with it because most people are not familiar of what the Tora truly says.
