We loosely talk of Self-realization, for lack of a better term. But how can one realize or make real that which alone is real? 

All we need to do is to give up our habit of regarding as real that which is unreal. All religious practices are meant solely to help us do this. 

When we stop regarding the unreal as real, then reality alone will remain, and we will be that.

Ramana Maharshi (1879-1950), Ramana Maharshi was an Indian Hindu sage and described as a jivanmukta (liberated being). He was born Venkataraman Iyer, but is mostly known by the name Bhagavan Sri Ramana Maharshi.
