To allow others to perceive something newly by seeing through your eyes is to contribute greatly to the world.
The very act of creative expression in this context is an intersection or apex of your dual realities. It gives you, the thinker, the reflective one the chance to be known, to relieve the inner loneliness that comes from flowing in a river with a deeper current than most.
It gives the opportunity for the world around you to interact with your inner world, to be given a back-stage pass if you like to the theatre of your heart. There is great joy in being known, especially in giving glimpses to such a core dimension of you.
Not only is there the relief of reconciliation and the joy of making yourself known however, but also there is the thrill that comes from presenting something valuable to those around you.
To serve others is to be enriched. To allow others to perceive something newly by seeing through your eyes is to contribute greatly to the world. To enable them the vicarious relief of getting something said that is so hard to put into words is no small service.
And so it seems the bridge of creative expression is a two way street, a servant that serves two masters by all at once providing the artist a way out, and others a way in.
