One of the guys that picked me up told me that his wife had read a book called Mikeemey ("lifted me up") written by an Israeli actress who returned to her roots. The author writes how when she started to repent, whenever she had problems with her car, she would say, "Na Nach Nachma Nachman MeUman", and all would be good. So one day this guy gets a call from his wife telling him that her car broke down and she is stuck. So this guy starts driving in her direction to help her out. A few minutes later he gets another call from her that all is good. He asks her how she managed that, and she tells him that she remembered what she read in Mikeemey, that when there's a problem with the car she said Na Nach Nachma Nachman MeUman and all was good, so she said, Na Nach Nachma Nachman MeUman, and all was good!
Another guy who picked me up, had beanie, no beard, no pehyos, no hair at all, he had two little kids in the back. He told me that he was in middle of reading a book from Rabbainu and started to tell me Torah from Rabbainu, and he was extolling the awesomeness of the Holy Land. It was quite amazing.
Another guy who gave me a ride, also with two young children in the back, told me that he was secular till about 10 years ago, when he started to observe the Torah (not in a chareidi way - he was wearing shorts). So of course he knew stuff from Rabbainu, but by him Rabbainu was just another Rabbi, but he was fascinated by Na Nach and he took his attention away from his children to pursue the topic of Nanach. He challenged me claiming that Nanach over-does the stature and importance of Rabbainu (which in truth is the opposite). Eventually he had to entertain the children, so I sang for them some hard core Nanach songs, and they got right into it B"H.... There's much more to this story, but it's hard for me to write. They got Nanached!
