|"We must first of all understand that our senses are imperfect. Just like we are sitting in this room. We have got our eyes, but we cannot see what is there, going on, beyond this wall. The sun is fourteen hundred thousand times bigger than this earth, and we are seeing just like a disc. So the eyelid is just near the eyes, but we cannot see what is the eyelids. If the light is off, we cannot see. So we can see under certain condition. Then what is the value of our seeing? If we, even if we manufacture telescope, that is also manufactured by the imperfect senses, so it is also not perfect. So anything understood by manipulating our imperfect senses, that is not real knowledge. So our process of understanding real knowledge is to take it from the person who has the real knowledge. Just like if we contemplate or speculate who is my father, it is never possible to understand who is my father. But if we receive the words from mother that, "Here is your father," that is perfect. Therefore the process of knowledge should be not to speculate, but to receive it from the perfect person. If we receive knowledge from a mental speculator, that is not perfect knowledge."
