There is some thread of wholesome clean living that permeates the Litvak yeshiva world and all those who walk in the path of the Gra and Musar. It is not something that I can put my finger on exactly, It is not physical cleanliness. Rather is is a sort of aura that a group has when it is devoted to good character traits.
But on the other hand there can be the problem that not every individual is like that. Even the leaders. Still the general feeling I have of that world of straight Torah of the Gra is that it exemplifies the peak of wholesome living. But one needs some sort of merit to stick with this.
