Refuah Shleimah Prayers for the Bima Ima's Sam

The Bima Ima's latest post on Superman Sam is that the doctors are hoping the create a "bridge" to ready Sam for  a blood marrow transplant.

Refuah Shleimah for:

Shmuel Asher ben Pessa Esther

A bridge?  If that's the case, then this is the song:
כל העולם כולו
גשר צר מאוד
והעיקר, והעיקר
לא לפחד, לא לפחד כלל

“All the world is a very narrow bridge, and the most important thing is not to fear at all.” Rabbi Nachman of Breslov
