I will try to give an anology to doing math:
I already know the result which I want to prove for my diploma thesis.
But I don't know how to get there step by step.
So this "knowledge" of the result, which I still am not able to prove, is a burden. Always thinking of the result that I already know, it is difficult to concentrate on actually exploring, step by step, from the little that I really know by understanding, without knowing how to breach the gap.
And it is like that not only with the end result. In mathematics it is often a problem, that one has to use results of others, which one has not proven or understood step by step by oneself. It would be far too time-consuming. So such knowledge becomes a burden, as one is "cheating" somehow, only using symbols without understanding anymore.
One can become really confused, collecting more and more "pieces of knowledge" that are everywhere available and seem to be related to the problem somehow. This might help. That might help. Without really understanding. In the end one might end up in the mental hospital. ;P Having lost the way back to humble "not knowing", knowing that one does not know, so that one is able to explore again, humbly from the beginning, with understanding which gives joy.
Maybe this is related somehow to knowledge of the Dhamma, and knowledge in terms of words vs. knowledge of the heart, without pretense and preconceived notions.
Knowledge in exterior things does not exist. That is the problem. But we have to use these means of exterior communication and understanding wisely and humbly, knowing that there is no knowledge in them. Even in our bodies and our minds there is no knowing.
Accepting this then one may be able to sit back and joyfully explore reality. Without "knowledge" that gives headaches, but with knowledge that gives joy.
So, just my thoughts. I hope they are useful in some way. Maybe I was spinning around too much. Before I become philosophical, I better try to get back to my math, fast.
Thank you for this topic. I would be glad to learn more and understand it better maybe.
I may translate this to German later. But anyone is free to do so if they like and see a purpose in it.
