Not attached. That’s it.
When you truly enter a meditative state, you don’t need music. No thoughts, no worries, right now.
But at the beginning, you can use some soothing music to relax yourself and help you become quiet. Generally, background music with the sound of the sea, mountain springs, or nature can be used as meditation music. Many yoga schools also have specialized meditation music. For example, Sahaja Yoga in India has a lot of meditation music that has energy. And a lot of music is specifically targeted at the three chakras and seven chakras.
In the beginning of the practice process of meditation, "seeing mountains is not mountains, seeing water is not water". Meditation is regarded as very complicated, and it is necessary to specifically eliminate distracting thoughts before entering tranquility. Later, "When you see mountains, they are mountains, and when you see water, they are water." The sounds around you and the people who appear are just like a painting or a play, they just appear. You just withdraw from meditation, even if you open your eyes, There is no reaction, no thought, no thought. This is meditation.
