So tarko 'pratiṣṭhaḥ śrutayo vibhinnā (CC Madhya 25.57, Mahābhārata, Vana-parva 313.117). If somebody says that "Well, argument and logic is not the way to approach the Absolute Truth. Then let us take scriptures, the authority of the scriptures," that is also very nice. In every human society there is some sort of scripture. Just like in your country there is Bible or any other scripture. We have got Vedas.
The Muhammadans, they have got Korans. They can help also, because that is also authority. But you will find that one scripture is differing from the other scripture in some details. Of course, on the average there is no difference. Just like Bible preaches, Lord Jesus Christ preaches love of God, we are also preaching the same thing, love of God. But our process is little different. That's all. That process may be different according to time, circumstances, people. That is natural.
Therefore, for a neophyte, simply by consulting scriptures, he will not be able to reach to the absolute goal. Because he'll find, "Oh . . ." Sometimes they become skeptic. Just like in the modern age, the youngsters, you all boys and girls, they are becoming skeptic. They don't believe in any scripture now, because they find some differences.
Therefore Bhāgavata said that tarko 'pratiṣṭhaḥ śrutayo vibhinnā (CC Madhya 25.57, Mahābhārata, Vana-parva 313.117): "Simply by argument you cannot establish what is Absolute Truth, and if you consult different scriptures, you will find difference of opinion, or difference of procedures, rituals."
