The phrase writing in blood is too old and also too dragged to death. The phrase, extensively used to signify a piece of writing utterly important to the author conveys by default much of what serious writing is all about. When you or I, any of us begin to write, what is it that we do? Is it not, an effort to wrench out the deepest of our emotion out and hope to do it justice through words?
The irony of the situation is, that words, through writing or through speech are no doubt the only medium for expression but they are nevertheless an insufficient medium? How shall one describe the scent of freshly falling rain on the mud or the feeling when a baby tugs your finger or just a simple reassuring smile from a stranger? Can you describe it?
Yet, it is my belief that one who writes well is blessed with a power of a vision that one not only creates for oneself but can powerfully induce into the mind of the reader. A piece of writing which emphatically stirs the thought of the reader without explicitly spurring him into action is one which is most near to accomplishing the actual purpose of writing. A collection of words that can intellectually challenge the reader and whose completion is possible only through the active participation of the reader’s imagination is a work that is remembered.
I am, of course, no one to set guidelines for what important works are and what are not. But of the little I know about writing, I know that a writer in his/her mind wants the reader to be engaged in what s/he writes. Not only is writing a way of expression for us, its like our melody, our magnum opus, our secret written out in metaphorical blood, our secret whispered to the paper.
