I gained a lot by being in Uman for Rosh Hashanah with Rav Nahman of Uman and Breslov in terms of learning Torah and music. But that is not to say that this is automatic that everyone ought to be there. To me it seems at this point that it is better to be in Israel. [עיקר הגלות הוא בגלל חסרון אמונה. LeM volume I section 7. The main exile is because of lack of faith.] And I ought to add that there was a period that I was trying to follow everything Rav Nahman said quite literally-- and that included coming to Israel. And in fact there was a sort of inspiration that I felt during that period which lasted seven years.
Nowadays I am not at all working on that program. Still I can see the great benefit in following the advice and ideas of Rav Nahman.
