Repetition turns a cry into a drumbeat. “Life” and “soul” point to the same person; the words tell us what she meant to him. The sentence is short because the feeling is simple and overwhelming. It reveals how deeply his sense of self was tied to her. The line compresses despair into a chant you can’t forget. Many people hear in it the way grief breaks language down to basics.
