Ignorance is not absence of knowledge. If it was absence of knowledge then things would have been very, very easy—and cheap. You can borrow knowledge; you cannot borrow being. You can even steal knowledge; you cannot steal being. You have to grow into it. Remember this as a criterion: that unless you grow in something it is never yours. When you grow, only then something belongs to you. You may possess something, but don’t be misguided by the possession. The possession remains separate—it can be taken away from you. Only your being cannot be taken away from you. So unless knowing happens into your being, ignorance cannot be dissolved.
Ignorance is not absence of knowledge; ignorance is absence of awareness. Ignorance is a sort of sleepiness, a sort of slumber, a sort of hypnosis; as if you are walking in sleep, doing things in deep. You are not aware what you are doing. You are not a light; your whole being is dark. You can know about light, but that knowledge about light will never become light. On the contrary, it will become a hindrance towards light, because when you know too much about light you forget that the light has not happened to you. You are deceived by your own knowledge.
It is as if you have been living in a dark cell. You have heard about light but you have not seen it. And how can you hear about light? It can only be seen. Ears are not the medium to know light: eyes are. And you have heard about light. And hearing again and again about light you have started to feel that you know light. You know about; but to know about is not to know. You have heard. How can you hear light? It will be as if someone says that he has seen music. It will be absurd.
