Question: If I do not really understand what the teacher tells me or I do not agree with what he says, does it interfere with my receiving the light through him?
Answer: You need to accept everything the teacher says as the absolute truth, and at the same time scrutinize it, because if you don’t agree with something, you must understand it and agree, since this is the reason that you develop.
No one is forcing you to close your eyes and agree with the teacher in advance, but you are called upon to accept his perspective and reach the state in which you will attain it and agree with it. If you begin to see flaws in it in advance, you will not advance.
