The importance of the Gra and the straight Litvak approach [note 1] came home to me today at the beach. I was resting there in order to gain enough energy to start back on my walk home. [And I was mulling over the sugia in Gitin page 86 and how it relates to two hazakot against one.] Then I saw some girls sit down to eat ice cream. Then one got up and went over to throw the wrapping away into the trash can. Then another did the same thing, and when the wind blew away what she had thrown out, she retrieved it and threw it away again. At that point, I could not help myself anymore. I went over and said, "You girls are the daughters of a Litvak Torah scholar." And of course they agreed. It could not have been more obvious. I asked where in fact their father had learned Torah?, and it turned out he had learned by one of the great Litvak yeshivas.
If you see someone who is has midot tovot [good character traits] and is careful about things between man and his fellow man [bein adam lehavero], then it is clear they are Litvaks.
[However far from Torah as I am, still I can smell the scent of true authentic Torah a mile away. ]
[note 1] I wish I could explain what this is exactly. The rough picture has a lot to do with Musar, but there is something else about it besides that. A kind of devotion, fear of God, and good traits.]
