Disclaimer: This question is not about religion, per se; however, it does have to do with jewish culture.
My rabbi had us sing some song during a few shabbats.
However, I don't remember most of the lyrics. I do recall one phrase: "life is a narrow bridge."
We sang it first in Hebrew, then English and Russian (all three had the same tune).
What is this song called, and where can I find the lyrics in all three languages (preferably with Romanization of Hebrew and Russian)?
