nature of true guru

Once I read that the true guru is the one who dispels ignorance in you, not the one who imposes his ignorance on you. But unfortunately most of the gurus or spiritual teachers of the present society are the ones who imposes their ignorance on you. A true guru is just like a undistracted mirror in which you can see yourself as you are, your greediness, innumerable fears, endless sorrow, conflict, continueous effort to become something, the division between me and not me....etc. It is your responsibility to show interest to clear all the dark spots of your mind, instead of doing this primary task most of us start worshipping that person(GURU), he will slowly become authority of our psyche and whereever there is authority there is no possibility of true learning, without learning mind becomes dull and shollow. The mind which is dull can only worship and become slave to the society. The one who is not pushing you towards the activity of self learning and only informing you few facts that he learned or stimulate you with his wardrobe and peculiar accent is not a GURU at all.
