Of course, in a large sense, a vibration or a sound means a lot, I think. But, here is a word called “a spiritual sound.” It is not music, and not to enjoy a sound. It is a spiritual sound. When I intend to cherish a spiritual sound, I think it is profoundly meaningful. I think there are lots of sounds which relax your mind, or make you peaceful, or make you approach being a so-called compassionate person. There are sounds which give you the opposite reactions, too. But if the music makes us or our minds peaceful as much as possible, I think such music gives a tremendous power.
