Any statement if it doesn't have proper narration will be useless word/s. For example,we all know total true colours are 16*16 = 256.If we leave first 16 colours and discuss about every next 16 colours,we get different canvass of mindset about same statement. That means sense is consistency against adverse questions. Whereas voice is NONLINEARITY(social four). So mind and sense are same.But voice is different from mind and sense.
