It is in the act of doing that progress might be made. You can only study so much and then you must, in order to complete the lesson, act upon what it is that you have learned. According to your level of perception you will either get it or not. Now, it does not in any way matter that you do not “get” a particular lesson. You might not be ready to get it. It might be three or four years from now before you are ready to understand all the ramifications, or at least some of them, of any particular lesson.
What will equip you to make real and valid progress with anything that you are learning is not to get the stuffed head about it. In this we speak of believing that you are the best in your field of endeavor. If you can always think of yourself as a student, as one who is constantly learning, even though you are able to teach now what you have learned, you will be able to improve upon that which you know now.
Our blessings to the chela.
