One of the books I'm reading on and off at the moment is "'Sacred Space, Sacred Sound' the Acoustic Mysteries of Holy Places" by Elizabeth Hale. She tries to draw some spiritual and scientific meaning to sound. How it's used in different religions rites and sites and it it's affect on those involved. Looking at both the present and historically.
One aspect I seem to remember is the concept that sound is absorbed and never disappears e.g. that the Rocks hear things and 'remember' i.e they have a memory. An interesting idea to reflect upon and let your imagination run away with.
The other night I was Reading Joshua 24 from the Bible and verses 26-27 are very interesting.
26: Joshua wrote these words in the book of the law of God; and he took a large stone, and set it up there under the oak in the sanctuary of the Lord.
27: Joshua said to all the people, "See, this stone shall be a witness against us; for it has heard all the words of the Lord that he spoke to us; therefore it shall be a witness against you, if you deal falsely with your God."
What struck me were these words 'See, this stone ...for it has heard all the words'.
One day I might look into this, the context and some ways people have interpreted this in years gone by, but for now I allow my mind to wonder, wondering if there is something far greater going on than we can begin to imagine. If objects like rocks can 'hear' then can it 'speak' and if it can 'speak' how do you hear what it has to say?
