The expression "beyond your ken" means something that is outside of your knowledge or understanding. It is used when someone is talking about a subject that you have never heard of before or that is too complicated for you to comprehend. For example, if someone is discussing advanced calculus equations, you could say it's beyond your ken because you don't have any knowledge in that area. It is a way to politely express that you do not understand something without sounding rude or unaware.
