Prabhupāda: So anyway, why this living entity is wandering, not fixed up? So there must be some goal. He is hankering after that. There must be some goal of life. To achieve that goal of life that is called sādhya. Why we are struggling here for happiness or something else? We are struggling. So this question was raised by Caitanya Mahāprabhu, that "What is the goal of life?" Unless there is goal of life, why there is struggle? Why... There must be some goal of life, sādhya. And sādhana. Sādhana means the means by which we can achieve that goal of life. That is called sādhana, sādhana. So Rāmānanda Rāya quoted... Because when there is talk between two learned persons, they... Just like nowadays it has become a fashion: "In my opinion," "I think in this way." What, nonsense, what you can think? What is your knowledge? But he is very proud. Everyone like that. The other day, that Sir Alistair? Alistair Hardy came. He also said, "It is my opinion." Nobody thinks that he is a nonsense number one; what is the value of his opinion? Nobody thinks. But this is the Vedic principle. Even Caitanya Mahāprabhu, He, when He was asked by Prakāśānanda Sarasvatī that "You are a sannyāsī. You do not engage Yourself in the study of Vedānta. You are simply chanting Hare Kṛṣṇa, Hare Kṛṣṇa." So... Because a sannyāsī is supposed to be always reading Vedānta philosophy especially and all other philosophy. So "What is this, that you are chanting like a sentimental person?" So Caitanya Mahāprabhu replied, "Yes, My Guru Mahārāja, spiritual master, saw Me a fool number one." So Caitanya Mahāprabhu, it was known to Prakāśānanda Sarasvatī, He was a great learned scholar in His student life. So He is posing Himself as a fool number one. So this is the way. Caitanya-caritāmṛta the author of Caitanya-caritāmṛta, he is presenting himself: purīṣera kīṭa haite muñi sei laghiṣṭha: (CC Adi 5.205) "I am lower than the worm of the stool." Purīṣera kīṭa haite muñi sei laghiṣṭha. Laghiṣṭha means lower, lowest. Jagāi mādhāi haite muñi sei pāpiṣṭha. Jagāi and Mādhāi was taken, they were drunkards, woman hunters. Therefore they were sinful. So Caitanya-caritāmṛta kahe, says that jagāi mādhāi haite muñi sei papiṣṭha. This is the way, nobody think himself as one has become very big man and he has his own opinion to give. This is rascaldom. So everyone should think that "What is my value?" That is really learned, humble and meek. Nobody should think that "Now I have learned everything. I can surpass everyone. I have become above all rules and regulation. Now I have become paramahaṁsa." This is rascaldom. Everyone should always think, "I am fool number one." Therefore the endeavor will go on, to become perfect. If we think that "Now I have become perfect, paramahaṁsa," then the spiritual regulative principles will never be followed, and you will fall down.
So here Arjuna also says that narake niyataṁ vāso bhavati iti anuśuśruma: (BG 1.43) "Kṛṣṇa, I have heard it from authorative sources." He never says, "Kṛṣṇa, in my opinion, if it is done like that, then people will go to hell." He does not give his own opinion. He says iti, "Thus," anuśuśruma, "I have heard." This is called paramparā system. Nobody should give his own opinion. He must quote the authoritative statement to support his proposition. So similarly, when Caitanya Mahāprabhu asked that "What is the aim of life and how to achieve it?" so Rāmānanda Rāya, he did not give his own opinion, that "In my opinion, like this." Here also Arjuna says, ity anuśuśruma, "I have heard it." He heard it means... Śuśruma means "heard from authority." So Rāmānanda Rāya said that "Real purpose of life, goal of life, is to satisfy the Supreme Personality of Godhead." Just like as we are citizens, what is our duty? We want to satisfy the authority, the government. When one serves the government nicely, in this country he is recognized as knight. He is recognized as earl, as lord, as... So many, they have got titles. Every country, when a person is very exalted citizen, then he is recognized by the government. So if this is the system in our ordinary life, then the aim of life should be to satisfy the supreme governor, or supreme government. It is very common sense. But they have no supreme government. They think, "Whatever government we make, that is final." No. There are so many kingdoms, so many planets. In each planet there is government, there is authority, and above all of them, there is the supreme authority, Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). This is the śāstric injunction. There are many controller. In this planet there is controller. There is another planet, another planet. Even Brahma is the controller of the whole universe. Just like in our government there is system. One department... Several departments is being managed by another director. Several directors is being managed by another secretary. As... The same system. Kṛṣṇa is the supreme proprietor, sarva-loka-maheśvara (BG 5.29), and He has got many secretaries, assistants. They are called Brahmā. So Brahmā means the manager of one brahmāṇḍa, universe. And there are millions of Brahmās, millions, trillions. They are numberless. Ananta-koṭi. Yasya prabhā prabhavato jagad-aṇḍa-koṭiḥ (Bs. 5.40). Koṭi. Koṭi means unlimited. Jagad-aṇḍa. Jagad-aṇḍa means universe. Brahmāṇḍa or jagad-aṇḍa. Aṇḍa. Aṇḍa means it is egg-shaped, round, egg-shaped. Therefore it is called aṇḍa, brahmāṇḍa. Bhū-gola. Gola means round. I have heard that before the science, the people were under the impression that this world is square. Is it not?
Prabhupāda: Flat. Flat, yes. But in the Vedic śāstra, millions of years ago it is mentioned: bhū-gola. Gola means round. Just see. And these rascals say that formerly people were not so intelligent. They are intelligent because they are thinking that this world is flat. And those who have spoken millions of years ago, "It is round," they will have less intelligence. Just see. Bhū, gola. Gola means round. Bhū-gola. Similarly, jagad-aṇḍa. Abda means round, just like egg. Aṇḍa means egg. Jagad-aṇḍa. This universe is egg-shaped. And we can see also, the sky is round. This is the wall of this universe.
