A thought on a thought....

It starts as a thought and then starts growing till it encapsulates my entire existence. I command it and then it commands me. I think about it and then it starts thinking me. A very small puny thought nonexistent just a fragment of my imagination slowly is transformed into an image that takes over my mind and all I do is find validations, examples, situations, something that someone said in the same context, movie dialogues, paper articles, the reference in the entire universe. Beyond a point it takes me on a journey of imagination and thoughts that leave far behind that simple thought that simple fragment. I wonder whether I am the master or the slave, whether I am the creator or the creation. Just a thought....
