Purpose. Plain and simple

I watched a movie today. The movie was Taare Zameen Par. What I realised had nothing to do with how I viewed the movie. It came from how I viewed myself. All of a sudden, amidst regret and the resultant silent resolve, I chanced upon my own interpretation of purpose. Purpose in life.

"Man's purpose in life is to look for that purpose which is bigger than his own life"
.............................................................................................................................................................................

"But, as you well know, appearances can be deceiving, which brings me back to the reason why we're here. We're not here because we're free. We're here because we're not free. There is no escaping reason; no denying purpose. Because as we both know, without purpose, we would not exist.
It is purpose that created us.
Purpose that connects us.
Purpose that pulls us.
That guides us.
That drives us.
It is purpose that defines us.
Purpose that binds us.
We are here because of you, Mr Anderson. We're here to take from you what you tried to take from us.

Purpose."
