Nonduality is the default setting of life. Nonduality is 'what is'. Most people seek 'the answer' to the inquiry. You understand Silence because of sound. Sound is not Silence, It comes from Silence, is surrounded by Silence and returns to Silence.
Life is relationship.
See 'what is'. I am the Unknown and it is constantly revealing Itself. If the framework of duality is a concept, Nonduality is as much a concept. When duality is all bananas, Nonduality is also, all bananas. See 'what is' - see the nature and function of things like words and the 'manifest'.
