What does it mean to truly understand something?

I apologize that I have not answered this question right now. I have to apologize, otherwise I will be very rude, I am British. I'm sorry:-)

On a practical level, I understand that understanding is helpful to me in my daily life. For example, because I understand the extent of abuse in the past, I can abandon my anger, nurture my compassion for people, find peace.

If something is true, it can be trusted. Therefore it is reproducible. Again, I have enough real existence (such as Buddhist emptiness and intermediate paths) enough to understand how you can see the horrible pain in the world and still find peace, I understand. I will use it to find peace, not so many humans, but the pain of animals and insects makes me feel depressed.

These are the ways I gained a practical understanding that is sufficient for me to use this theme in my daily life. I do not know if I really understand something. This is a very deep question, but is there really a problem? I have seen so much that I do not know and I can not even know. "I do not know" is part of surrender, bringing part of the deepest peace.

I do not doubt it. There are not so difficult topics. There is no exception. Does this mean that I open a book on neurobiology and can learn everything after reading once? Absolutely not. If I can not understand something, that means I lack the basic concept of that field. In this case, learning concepts after closing the book. I reached several concepts I already knew and built from there, then it recursively repeats this until I return to the topic I began to learn. I regard everything I have learned as a model for expressing real things. Science is the pursuit of a model that best represents the truth. However, since all models are defective, I adjusted the depth that I need to understand right now. I can not fully understand the topic, but it is possible to achieve an understanding of the level that meets my curiosity and make this knowledge applicable to my life. However, when I reached this point, I do not think that this topic is still "completed".

Understanding is strange. Do you understand what that means? What should I do? While studying the exam, the student "clicks" it once in the textbook, then twice and then, then on the third reading, and he understands. What is the term of "click"? This is a moment. The process of understanding something happens instantly. It had not been for a while, suddenly we owned it. From this understanding, we can create ideas. Indeed, the factory's example above is not entirely correct. Verbal recognition is not a material of original thought, but a place where the whole thought process is carried out (Note: "verbal" cognition has changed from spiritual to psychological objective The word used to explain experience seems to have failed in the subjective field.
