If we talk of knowing the Self, there must be two selves, one a knowing self, another the self which is known, and the process of knowing. The state we call realisation is simply being oneself, not knowing anything or becoming anything. If one has realised, one is that which alone is and which alone has always been. One cannot describe that state. One can only be that. Of course, we loosely talk of Self-realisation, for want of a better term. How to 'real-ise' or make real that which alone is real?
