There are three reasons for this problem: first, you read the original text, and your foreign language level is limited, so you can't understand the meaning of poetry; The second is that the translation you read is not good enough, so that you can't understand the meaning of poetry; The third is that there is nothing wrong with the writing itself, but you have a poor foundation and can't understand the meaning of poetry. The first solution is to find a suitable translation version, then the second problem is solved. It is not easy for readers to enter profound texts, and a lot of preparatory work is needed. For example, we are reading Homer's epic and medieval German heroic epic. If you don't understand the historical background and European cultural traditions at that time, such as the culture of ancient Greeks or the spirit of Germanic barbarians, it is difficult to understand why there are so many bloody and violent events in the epic. Of course, this is only a basic knowledge, as well as basic literary common sense, philosophical common sense and even classical language common sense, all of which are necessary introductory tools. The so-called aesthetic pleasure does not mean that you are happy after reading it, but that it is difficult for you to gain aesthetic experience through constant thinking, constant learning and constant knowledge. This process is satisfactory.
So in the final analysis, when you encounter something profound, you should either put it aside first and start with other simple basic knowledge, building it brick by brick. I believe that one day you will reach your ideal height.
I wish you progress!
