Simply by argument and logical conclusion, you cannot approach to the Absolute Truth, or real truth. Tarko apratiṣṭhaḥ śrutayo vibhinnāḥ (CC Madhya 17.186). And if you consult yourself scriptures . . . just like Bhagavad-gītā, if you read yourself, you get one kind of impression, and if you hear explanation from an authorized person, you get another impression. The book is the same, but by hearing from the authorities, you get a better impression, better understanding. There are so many examples like this. Tarko 'pratiṣṭhaḥ śrutayo vibhinnāḥ.
Now, there are many scriptures in the world. The Hindus have got the Vedas; the Christians have got the Bible; the Muslims, they have got Koran. Now, if you read all these scriptures, you will find something contradictory. Just like animal killing. Animal killing, more or less, there are in every scripture, restricted or non-restricted.
There is none non-restricted; restricted. Even in the Koran, the animal killing is restricted. Animal is to be killed in the . . . in certain Bakri Eid ceremony and in the masjid. Similarly, animal killing amongst the Hindus, they are to be done in the temple of Goddess Kālī. But no slaughterhouse is recommended.
Anyway . . . so if you read different scripture, you will be bewildered. In one scripture it is said . . . but there is adjustment. If you go to the authorized person, he can adjust. But you cannot see. You see . . . you'll see contradiction. So śrutayo vibhinnāḥ. Therefore they are considered different, but actually, they are not different. Śrutayo vibhinnāḥ. Tarko 'pratiṣṭhaḥ śrutayo vibhinnā nāsau munir yasya mataṁ na bhinnam.
And there are speculators, so-called philosophers, putting theories and doctrines. So one doctrine is different from another doctrine. And people are convinced that no doctrine is absolute; therefore they are going on searching doctrine after doctrine throughout the whole life, and they do not know . . . just like the theosophists. They go on, simply searching. They have never come to the conclusion, "Here is the end." They cannot do that.
But in Bhagavad-gītā you will find, "Here is the end." Kṛṣṇa says, mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7): "My dear Arjuna, here is the ultimate goal, I am—Kṛṣṇa. There is no more anything higher than Me." Nānyad asti kiñcid dhanañjaya. Mayi sarvam idaṁ protaṁ sūtre maṇi-ganā iva: "Just like in a thread, the pearls are woven, similarly, everything is standing in Me."
