I must tell you I'm quite shocked by some of the responses here with regards to the Tzaddik of B'Kerestur. I never realized how great the machloh is today - the lack of emunas tzaddikim. And we're not talking about today's gutte yidden either, we're talking about people who weren't born with a silver sppon in their mouths, but made a name for themselves the hard way, by helping others and saving lives. I'm stunned at how some of the same people who supposedly stand up for "real Torah values" can so nonchalantly make such disparaging remarks that even a goy in his time - as well as twenty years later - would not make! Now, I'm not gonna stand here and tell you to take a minyan and ask mechilleh at his resting place; I'll leave that for you and your collective conscience to bear. Somehow we decided that greatness in Torah should be the only measuring stick to see whether or not there is tzidkus as well. I can bring you this: most of you - even the skeptics would agree about his d'veykus to the Eybershter, besides for that fool who compared to the TA"Y Rebbe. Interestingly enough, the Alter Rebbe, Rav Schneur Zalman of Liadi, author of the Tanya and the Shulchan Aruch HaRav, says otherwise. In his opus primum, which was warmly approbated by the greats of his day, the Alter Rebbe brings proof from the Chassidim HoRishonim, who would spend some 9 hours a day thinking about G-d, and connecting to him ביראה ואהבה עזה ודביקות אמיתית, proving to us that not only was this not bittul torah, but this service of Hashem was greater than the study of Torah! Is that good enough for you all?!
