You have to be changed, utterly changed. You have to be burnt, in toto. Your expectations come from your mind; your mind has to be destroyed. Only then and only then is God possible. So how can a real Master fulfill your expectations?
People go on changing from one teacher to another. A few days they are on a honeymoon with one teacher, and then as every honeymoon fades away, after a few days they are finished. When they first come across a teacher they are very enchanted; it seems as if now the time has come for fulfillment of their desire. But soon knowledge is supplied, and knowledge cannot quench your thirst.
