Fear is a vital response to physical and emotional danger—if we didn't feel it, we couldn't protect ourselves from legitimate threats. But often we fear situations that are far from life-or-death, and thus hang back for no good reason.
Spirituality means something different to everyone. For some, it's about participating in organized religion: going to a church, synagogue, mosque, and so on. For others, it's more personal—some people get in touch with their spiritual side through private prayer, yoga, meditation, quiet reflection, or even long walks.
