It is only your ignorance that makes you say: I know

Q: Ignorance of what?
M: Ignorance of yourself primarily. Also, ignorance of the true nature of things, of their causes and effects. You look round without understanding and take appearances for reality. You believe you know the world and yourself -- but it is only your ignorance that makes you say: I know. Begin with the admission that you do not know and start from there. There is nothing that can help the world more than your putting an end to ignorance. Then, you need not do anything in particular to help the world. Your very being is a help, action or no action.
Q: How can ignorance be known? To know ignorance presupposes knowledge.
M: Quite right. The very admission: 'I am ignorant' is the dawn of knowledge. An ignorant man is ignorant of his ignorance. You can say that ignorance does not exist, for the moment it is seen it is no more. Therefore, you may call it unconsciousness or blindness. All you see around and within you is what you do not know and do not understand, without even knowing that you do not know
and do not understand. To know that you do not know and do not understand is true knowledge, the knowledge of an humble heart.
