BUT THERE ARE MANY OTHER TZADDIKIM WHO ALSO WROTE INSPIRATIONAL AND LIFE SAVING TEACHINGS TOO? WHY DOES REBBE NACHMAN STICK OUT?

BH

Reb Noson, Rebbe Nachman's main disciple writes in the book: REBBE NACHMAN'S WISDOM, that even today after Rebbe Nachman's passing, his teachings have a unique power and ability to wake up and arouse people to come back to Hashem.

The only way to see the difference between what Rebbe Nachman's teachings can do to a person vis-a-vis other books and teachings is to simply do an experiment of learning his teachings for a while and then see the change for himself.
