Give me headphones. Eyes closed. Full blast. Let the sound fill every crag of my mind. Let the body fade away until all that remains is a head swimming in the sounds of melody, harmonies, lyrics. Relax all thoughts until they melt away. Every worry, love, hate, emotion dissipates until the warmth of musical connection is the only feeling traveling through muscle, nerves, bone. Then, pure meditation through music can be achieved.
A single second may be all that a mind can muster. Brain tends to kick in. But practice, practice, practice can extend this enlightenment. Reeelax. Take it all in. Don't think. Just feel. This is what it is to listen.
