Critical voices in the head probably started off with good survival objectives. How to deal with encountering a bear or a storm. Critical thought probably saved the day. That’s why meditation watches the breath, or a candle, or letting thoughts come and go. It relieves the dialogue that otherwise runs the show without stopping. And when there are no bears or storms the same mechanism chooses whatever else it can, like you and everything that’s wrong about you. What do those voices have to do with performing or writing music? Nothing, but it can’t stop itself. The trick is to dilute the concentration, seeing it for the software it is is like exposing superman to kryptonite .
