What is the difference in inner dialogue in happy vs unhappy people?
I guess the inner voice is what one strives to just observe and let be while meditating. After a good meditation session I feel less mentally tense (eg not clinging on to superficially important todo items).
Seems like inner voice is related to mental state in a major way. I have pretty severe adhd and am unmedicated so my inner voice is more like an old radio inbetween stations (= chaotic).
