I tend to agree with Rhonda M. Our thoughts radiate and can be picked up by anyone - and probably are - at a subconscious level deep beyond our ken. Whether those who no longer live on Planet Earth wish to tune in to those radiated thoughts would depend, I expect, upon their interest in either us, the subject matter being thought about, or both. If they do 'tune in' then they receive what we're thinking or have already thought. I don't think they would 'read' a 'pshysical world' printed page as we do.
I'm also open to the belief that during the day when we are 'thinking' we are not so much thinking as picking up and modifying with our own personal thinking aparatus - the vocabulary in our minds - those radiations and make the mistake of assuming that they are simply our thoughts - completely original to us.
To tune out of the 'mind flow' or verbal thought takes a lot of training and discipline, but when one can do it, it puts a different perspective on thought altogether.
