If you can speak on some subject matter for four hours, how it is zero? Just see the contradiction. Gaurasundara, you were present when he was speaking? You heard? If I can speak something on a subject matter, is that subject matter zero? Zero means śūnya. Śūnya means nothing. So how you can speak on nothing? If you can speak on nothing, then nothing is no more nothing. It is something. Just see. But you are so proud. "Oh, he spoke on zero for four hours." I did not contradict because he is newcomer, but I talked on other subject. But this is the position. Suppose you can talk on zero for four hours. Then either you waste your time . . . because after all it is zero. The result is zero. Just like you add one million zeros. So what is the value? Zero. So who is a fool that knowing that one million zeros makes zero, why shall I waste my time making so many zeros? So either he is a fool or if zero has so much substance to speak, then how it is zero? If zero has so much value that one can speak on it for hours and hours together, then how it is zero? So people do not understand things very properly. They're so dull.
Then he was eulogising the man who spoke on zero for four hours. Yes. That is the system, if you hear a man talking nonsense and people will give cla . . . oh! And he's asking what you have understood, "Oh! it is very difficult to explain." Then why you are wasting time? If you cannot express, if you do not understand. Simply people wants jugglery of words, they don't want substance. They don't want substance. That is the difficulty in the mod . . . in the present age. Sva-karmaṇā tam abhyarcya saṁsiddhiṁ labhate param (BG 18.46). Svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam (BG 18.46). So you should learn this nice simple fact, that whether by your work Kṛṣṇa or the Supreme Personality of Godhead is being satisfied. Just like a student, how he is prosecuting his studies will be tested at the examination how he can satisfy the examiner. Similarly, whatever we may do, we have to enquire or to understand whether by that work the Supreme Personality of Godhead is satisfied. Unfortunately, they do not believe in God, or if they had some ideas of God . . . now they say God is dead. So they do not think that it is necessary to please God. That is the difficulty.
