We are concerned in bringing about a mutation of the mind. To bring about such a revolutionary change within yourself, you have to listen, not accept, not deny, not compare, but just listen, which is quite a difficult thing to do. For most of us, whenever we listen to something, we are either justifying it, comparing it with what we know, or referring to some authority that we have established for ourselves. When you do that, you are not actually listening; you have deviated, you have moved away.
