If you want to enter into the spiritual world, you cannot get through simply by arguments. Because there is no limit of argument. I place my argument in one way; another man, who is better arguer, he places his argument in a different way. So if you simply go on arguing, it is not possible. Tarko 'pratiṣṭhaḥ. It will never help you, argument.
Śrutayo vibhinnāḥ. If you think that, "I shall read scriptures and I shall understand God," no, that is also not possible. Śrutayo vibhinnāḥ. Scriptures are also different, because scriptures are made according to time, circumstances, people. Just like Bible. Bible, Lord Jesus Christ preached in the desert, Jerusalem.
Or where it is? People who were not so advanced. Therefore his first instruction is, "Thou shall not kill." That means they were very much engaged in killing affairs, otherwise, why is this instruction? And actually, it so happened that they killed Jesus Christ. So that society was not very enlightened society.
So a scripture for a society which is not very enlightened and a scripture for a society which is very enlightened must be different. Just like a dictionary. For the schoolboy, a pocket dictionary, and for a college student, international big dictionary. Both of them are dictionaries, but the small pocket dictionary is not equal to the big dictionary—because it is different made for different classes of men.
So scriptures are made according to different classes of men. There are three classes of men: first class, second class and third class. The third-class man cannot understand the philosophy and scriptural injunction of the first-class man. That is not possible.
Higher mathematics cannot be understood by the small schoolboys who are simply trying to understand, "Two plus two equal to four." But "Two plus two equal to four" is equally good to the higher mathematics student. But still, higher mathematics and lower math is different. Therefore it is said, śrutayo vibhinnāḥ: the scriptures are different.
So if you simply try to understand what is God by reading scriptures, you cannot achieve. You must approach a guru. Just like a medical book, it can be available in the market. If you purchase one medical book and study and you become doctor, that is not possible. You must hear the medical book from a medical man in the college, medical college. Then you will be qualified. And if you say: "Sir, I have read all the medical books. Recognize me as a medical practitioner," no, that will be not.
So śrutayo vibhinnāḥ. Scriptures are different. Arguments, that is also not helpful. One man may argue better than me. Then philosophy: The philosophy, it is said, nāsau munir yasya mataṁ na bhinnam (CC Madhya 17.186). One philosopher is differing from another philosopher. Just now today Śyāmasundara has purchased one book about different philosophers. So that, you also cannot ascertain what is truth. Therefore śāstra says, dharmasya tattvaṁ nihitaṁ guhāyām. The truth is very confidential. So if you want to know that truth, mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186), you should have to follow the great ācāryas. Then you will understand.
