Duality into non-duality.

We use duality in an attempt to describe non-duality. We ask 'who am I' in an attempt to know our true nature. But how can you divide in non-duality? That which we are is both nothing and everything and language is never enough. Ramana Maharshi was said to use the concept of taking a thorn from a tree to use as a tool to remove a thorn embeded in the skin. When the thorn is removed both thorns are thrown away. Language is part of the duality of life and so we have to use it but inherent difficulties arise when we try to describe non-duality. The term 'poiters' is used instead of 'truths'.
