It is not possible to come to the right knowledge by so-called research, because our senses are imperfect. Just like we see through the telescope and we come under certain conclusion, but the fact is that I am the same person seeing through the telescope, and telescope is also manufactured by me or by you. So machine is imperfect and my seeing power is also imperfect. Then how you can have perfect knowledge? The machine is created by a person who has got imperfect knowledge, and the seer is also a person; he is also imperfect. The imperfect person is seeing through the imperfect machine. Then how we can conclude perfect knowledge? This is not possible. Therefore the method is, according to the Vedic knowledge, that if you want perfect knowledge, then you should approach the perfect person.
