Do the witches infact have any power in the play macbeth ...

Its oft I had been asked by students and many of others of the given topic. What I personally felt be its answer, referring obviously standard books, I answered my seekers including also analyzing myself many times just twelve lines of the opening scene, which is in fact, later I thought, is containing a very ‘partial fulfillment’ of the conversation among the witches- perhaps that figures out the destiny of a mortal being, destiny of our tragic hero, full of “profound- mature -complexity of human materialistic nature’’.
