Is meditation with music constructive, destructive or does it even matter?
Really it does not matter for me. Meditation may spring from any kind of input including a car alarm or Bach or sunset or massage. Any experience at all points only and always to consciousness/awareness. By quickly letting go of the attachment (grasping or rejecting) of any experience then the meditator ‘itself’ is all that remains to be the subject. That subject would now remain to be the actual awareness of the experience. There is no separation between the subject and the object of meditation in this way. This is release!
