I play the violin and I love the way that classical music resonates and stirs up different emotions in me like you well described @bestgift.
Playing is the only way I have ever experienced that real flow feeling; when I listen to it (what I'm playing alone or with the orchestra, or with quartet), concentrate and put my soul into it, I can loose track of time completely and feel very deeply touched and emancipated. It can be very purifying experience.
