Buddhism is not a theistic religion, so it does not have to deal with issues of ‘creator’ and ‘created’ and whether they are divisible or indivisible. Duality and nonduality are concerned with being and not-being – with existence and non-existence. That is why we speak of emptiness and form rather than ‘creator’ and ‘created’.
In terms of meditation we speak of the nature of Mind, and that which arises as being non-dual. In terms of the ‘meaningfulness’ of eternalism and the ‘meaninglessness’ of nihilism – nonduality allows meaningfulness and meaninglessness to be simultaneous facets of reality. Meaning arises out of meaninglessness, pattern arises out of chaos – and they are undivided.
