There is a Navajo lullaby that my grandpa used to sing to me when I was a little girl.?

Does anyone know the actual lyrics? It sounds like, "she no shaa", and it means, "there are many paths you must walk alone." Julia Begaye also recorded it at one time. It was also featured in the movie Outlaw Josie Wales, but the person just played it on the flute as background music. I want to teach it to some small children, and want to make sure I'm teaching the Navajo words correctly. Please help, and don't respond, "just jump around a fire yelling Hi How Are Ya?" THANKS.
