What is the symbolism inherent in Kino's bar?

After Kino struggles through the pain of his marriage's dissolution, he decides that the best course of action he can possibly take was to "create a place where his heart--devoid now of any depth or weight--could be tethered, to keep it from wandering aimlessly" (152). Therefore, the bar symbolizes a sense of belonging and a sense of place for Kino.
