Defining spirituality is difficult.  If we attribute it to a god, we miss that many unbelievers attest to having spiritual experiences.  If we assign it to a nebulous immaterial presence, we encounter the problem of making something amorphous into something that is physically real.  And if we say that spirituality is thoroughly human, we run into the perennial dilemma of understanding how consciousness can emerge from inert matter.

     Wassily Kandinsky, a Russian surrealist painter and whose birthday we will remember in December, thought much about spirituality, spirituality in regard to art.  He did so as a way of explaining how art overwhelms what he considered to be the spiritual darkness of Marxism.  Whether or not one believes in God, Kandinsky observed, we all benefit from the spiritual benefits of art.  In art, we feel hints of transcendence, intimations of things we cannot easily fathom, emotional insights that we do not experience otherwise.  We look into another world, a world of light, real or imagined, a world that eclipses the rigid (and often absurd) materialism of the Marxist worldview.
     Kandinsky's art reflects his words aptly.  It is highly abstract and difficult to fathom easily, but that's the point:  spirituality isn't supposed to be simple.  If it were, it would be no more than another product of our material human whims.
