Great looking.If I swap radio for song, as I think of radio as the actual machine that's plugged in. So if I say I hear a song instead. But actually what is a song -, sounds, which mind might label, music, or words. But 'song' is not the actual experience of a song. Music and words are not ae of music or words. Words cannot capture the experience of sound. So yes I can see, radio or song, neither are actual experience.
Let’s try the following experiment to help make what is being pointed at, clearer.
We are looking at the raw experience labelled as sound and ignoring the thought ABOUT what the sound is as described by thought.
For this experiment you will need to sit yourself near a clock that has an audible second hand. If you don’t have a ticking clock, then here is a link to a clock on Youtube. Do this experiment several times.
Take in a couple of deep breaths and close your eyes.
Listen to the sound. “Tick tock tick tock tick tock tick tock”
Focus on the tick tock. Attune to the sound itself. IGNORE all thoughts and mental images about what seems to be creating the sound.
Try to find the clock.
Going just by the tick tock sound, do you find a clock present?
Is there any direct/actual experience of a clock in the sound?
Does the sound come self-labelled as originating from the clock?
Do you find a clock hidden in the sound?
Do you find a clock beyond the sound?
In your direct/actual experience of the sound, do you find any evidence that the sound is caused by a clock?
What do you find?
Allow your eyes to open.
Were you able to establish that in your direct/actual experience of the tick tock sound, that there was a clock?
