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."
So if we read different scriptures, then we are also bewildered and we cannot come to the conclusion by arguments. And nāsau munir yasya mataṁ na bhinnam. And if you read different speculative methods or philosophical doctrines, that is also different from one another.
Because the philosophy . . . one philosopher is big philosopher if he can defy his predecessor philosophers. Matam na bhinnam. Therefore, dharmasya tattvaṁ nihitaṁ guhāyām. Therefore the truth of a religious path is in oblivion. How one can understand what is actual Absolute Truth, what is the religious path?
The last instruction is mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). Therefore you have to follow the footprints of authorities.
