Poetry, music, myth, and metaphor are all ways to keep in touch with our souls, to let them have their place in our lives. Without them, we can easily get locked into a drab reality. Reality becomes drab because we're denying parts of ourselves, the parts that are JUST about feeling - feeling hope, feeling love, feeling that life has meaning.
I always hated it when my mother said 'It's JUST .....' when referring to anything spiritual or inspirational. Like, 'It's just some silly poetry, nothing of any significance or value.' Just ?! It's just a broken heart, just a feeling, not a concrete thing of any value.
