The bottom line is spirituality means something that touches you and can touch other people as well. It’s the idea that art is a kind of mirror. You create something in a very selfish way and then when you release it into the world, it becomes a mirror. If other people see themselves reflected back in what you’re doing, then there is a sense of touching people. Touching people means making people understand that they’re not alone in feeling the emotions they’re feeling. In that sense, spiritual music is about making people feel they are part of a collective consciousness. None of the things we feel in this world are unique to us, no matter how bad or good they may feel.
