HH this post is in the merit of Faigy Weiss one of my holier friends on Facebook may H"Y bless her and shine for her the light of Na Nach Nachma Nachman MeUman!
Rabbi Nachman said that even a huge tzadik and talmid chuchum is probably going to violate the Shabos in some way (on his level), the rectification for this - Rabbainu revealed - is to eat a lot of good food on Shabos, thus honoring the Shabos which rectifies all the violations. So as you see the main thing is to sing Na Nach Nachma Nachman MeUman! [in the litvak world they were also worried about not being able to guard from desecrating the Shabos, so they propounded the daily study of the laws of Shabos. Rabbainu however saw past this, revealing that even a tzadik who knows clearly all the laws of Shabos can run into problems, so they are chasing after a false lead, the answer lies in changing one's attitude to that of Shabos, and then everything will be smooth and holy B"H).
Rabbi Nachman once asked Rabbi Nussun how he feels on Shabos, and Rabbi Nussun answered that sometimes he feels "frum" (i.e. fear of Heaven), and Rabbainu told him that he was mistaken - the main thing on Shabos is to be happy very happy! Later Rabbainu warned Rabbi Nussun not to get worried about being able to be happy on Shabos - just be free to be happy!!!! So as you see the main thing is to sing Na Nach Nachma Nachman MeUman!
