I cannot find two famous saying attributed to Rebbi Nachman of Breslov.
- The whole world is a very narrow bridge...
- It is a great mitzvah to be happy constantly
Instead I have found
- A man must traverse a very narrow bridge... (I forget the exact location, I believe in likuteh morahan tinyana 8)
- A brief sicha extolling the value of relating to the shoresh of simcha (likuteh moharan tinyana 34)
Are these famous saying merely misquotes? Do they have other sources either in the works of Rebbi Nachman (or his students) or elsewhere?
