So ladies and gentlemen, I thank you very much for your taking so much trouble in participating with us in this great movement of Kṛṣṇa consciousness. As I am repeatedly placing before you with all humbleness that this movement is very, very much essential, not only at the present moment, but also all the time. And specially in this age, Kali-yuga, the age of disagreements and quarrel. Kali-yuga means nobody agrees with anyone. Everyone has got his own opinion, however condemned it may be. And on that point everyone is prepared to fight with one. Therefore it is called Kali-yuga. So putting different theories, philosophical speculations, will not solve the problems of the world, because not only during this age, but in all other ages also, there are different philosophers, different scriptures. That is the law of this material nature. Here there is no oneness. Duality. This world is meant for duality. So it is called dvaita. Dvaita means duality. So Kṛṣṇa dāsa Kavirāja Gosvāmī, he says, dvaite bhadrābhadra sakali samāna, ei bhāla ei manda saba manodharma. In the world of dualities, bhadrābhadra, "This is good, this is bad, this is nice, this is not nice," they are simply mental speculation because in this world nothing is nice. Everything is bad because it is not eternal. Therefore Śaṅkarācārya said, jagan mithyā, brahma satya. That's a fact. These, anything, the varieties of this world: temporary. That is the right word. It is not mithyā; it is temporary fact. The Vaiṣṇava philosopher says that this world is not false, but temporary, anitya. Anitya saṁsāra moha janmāile (?).
Śrīla Bhaktivinoda Ṭhākura said, jaḍa-vidyā saba māyāra vaibhava: "Advancement of material science is increasing the illusion of māyā." We are already illusioned, and if we go on increasing the illusion more and more, then we become more and more entangled. That is the nature. And so long we are illusioned, we shall put forward different theories, different philosophies, and different arguments. Therefore śāstra says, tarko apratiṣṭhaḥ (CC Madhya 17.186). Simply by argument and reasoning, you cannot make any spiritual advancement. Because you may be very good, I mean to way, logician, putting forward nice arguments, but somebody may come who is better than you. He will spoil all your logic, and he will establish his own logic. That is nyāya-śāstra. In Sanskrit there is nyāya-śāstra. So they are taught how to defeat his opponent. Therefore the Absolute Truth you cannot understand by argument, by material dealings.
