Answer: To hold on to the teacher and to feel the teacher are two different things. To hold on to the teacher means to try to do everything he advises you to do, to learn everything that he teaches you. You can hold on to the teacher only if you fulfill all his requirements and help him, even perhaps in his daily life, but mainly in the process of the study and dissemination.
Dedicate yourself to serving not the person, but what he represents, and then you will discover that this is how you begin to attain the upper world.
