Poetry is a mirror of our soul but also a window to the outside world---that which is external and tangible--neither is complete without the other
but it's only the inner side of us that understands the deeper meaning of life and all things.  It's strange but true---the intangible is mysterious, profound and has power and resources latent within us--most of which we aren't even aware---until kindled and brought to light by the muse of poetry.  Then a clear light dawns upon us and we begin to see and understand things better.  The 'physical we' is, in my view,  of lesser significance than the 'abstract we' or should I say the 'essential we'?---that which can be seen, handled or articulated is only the periphery of truth and things but not the core--we are larger than what we think  but we don't grasp this as we are lost in the banality and humdrum of daily life--we are walking shadows rather than light and fall short of our real potential. Talking of language and music, Felix Mendelssohn wrote (my paraphrase):
words mean less to me than music and it's music that speaks clearer to me.
        All said, man is a mystery as life is but they intersect--at every point.
