Prabhupāda: Pramāṇa, there must be evidence. Otherwise... Just like science means simply not to see observation that things are taking place, but experiment. It must be substantiated by experiment. Just like theoretically everyone knows that two chemicals, soda and alkali, mixes together and there is interaction, effervescence. But who is mixing the soda and alkali, er, alkali and acid? There must be. Therefore the answer is there in the Bhagavad-gītā, mayādhyakṣeṇa prakṛtiḥ suyate sa-carācaram (BG 9.10). "Under My superintendence." That is God. Under God's superintendence things are coming. Parasya śaktiḥ vividhaiva śruyate. He has got many multi powers and energies, they are working. Just like in nowadays electronic. You type your "a" and thousand miles away another typewriter will strike immediately "a", is it not? It is called, what is called?
Paramahaṁsa: Telex.
Prabhupāda: Telex? Not telex. Telex is also on the same thing.
Devotees: Teletype.
Prabhupāda: Teletype, yes. You push here "a" and the other end the "a" will immediately strike. There is no need of another person typing. But how it is being done? There is electronic arrangement by higher scientist. Not that, ordinary typewriter will not, no. Suppose if you keep one typewriter at your brother's place and you push it here, will it strike there? (laughter) Why? Because there is no arrangement. There is no arrangement. So these are common sense but the rascals will not understand. That without a touch of the living entity nothing can be done. The supreme living entity is Kṛṣṇa. Therefore it is said mayādhyakṣeṇa prakṛtiḥ suyate sa-carācaram (BG 9.10). "I am the cause of the material energy working."
