Prabhupāda: But that is the tendency of modern... They do not accept that their senses are imperfect. They want to see something, distant place, with microscope... What is called? Telescope. Telescope. But the telescope is manufactured by you. It is imperfect.
Professor: But I would say that even in India, where ancient tradition... They would propose how to arrange our telescopes to be able to see more correctly.
Prabhupāda: You have to see... That... Vedic injunction says, śāstra-cakśuṣā. Śāstra-cakśuṣā: "Your eyes should be the śāstra." There is another crude example. Just like who is your father? How do you understand? Through the vibration of the mother. The mother says, "He is your father." You accept it. Otherwise there is no experiment. So things which are beyond your perception, beyond your defective senses, that should not be speculated. Na tāṁs tarkeṇa yojayet. Acintyā khalv ye bhāvā na tāṁs tarkeṇa yojayet. These are the injunction. What is beyond your perception, beyond your speculation, don't waste your time so-called argument and logic. What is argument? Mother says, "He is your father." Where is the argument? You cannot apply any argument.
Professor: No, I said old tradition in India has been going on into argument itself.
