This question posed by Sri Ramana Maharshi invites us to inquire into the very nature of our existence. The inquiry itself leads us past the wide spectrum of all the names that we are given at birth along with all of those labels, expectations and opinions that others seem to tag upon us at every juncture. Further investigation reveals that we are the best of friends the moment we please someone and then, denigrated by a judgmental look of disapproval the instant we say, "No" or otherwise happen to take a different standpoint.
It is such a blessed chance of luck when we realize that no concept can possibly capture the essence of who we really are. Suddenly, we are able to turn inward and ground ourselves in the source of our own true Self. No longer is there an attempt to live up to someone else's portrayal of what they want us to be. Never again does anyone have to be wrong. Imagine that: we can all be right. Moreover, we can see one another in the light of such innocence!
And when all of the molds and mirrors are broken and left on the barren, red earth like cracked clay pottery, discarded from years of overuse, we can actually celebrate this wearing away of our persona. Indeed, the secret of secrets is that we have never been a mere perception or a word handed to us in childhood. What a relief it is to experience that we are the entire universe and all the spaciousness that lies hidden beyond.
