This music helps you to recognize the pattern of sadness, that it is active in you and "transform" - to "convert" into the peace that follows. For the dissolution of sadness conveys a sudden feeling of peace deep down in the depths of your heart, in a knowledge that you now have the power and strength to create peace within yourself.
Sadness is sometimes nothing more than a "trained" pattern, a blockade that is largely completely out of step with the situation, is even active for no apparent reason and can thwart goodness in your life. Converting means simply converting one "file format" to another! In this sense: with the help of music and meditation, transform your old file format, which you no longer need to turn into a new one!
