Na tāṁs tarkeṇa yojayet. Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet (Mahābhārata, Bhīṣma parva 5.22). Simply by arguments, logic, you cannot understand Kṛṣṇa. That is the Vedic injunction. Tarko apratiṣṭho. You cannot establish the truth by simple logic and arguments. You may be very great logician, but somebody may come who is greater logician than you, and he defeats you. That is going on. Tarko apratiṣṭha śrutayo vibhinnām.
Now, if you read the Vedas, you'll find some contradiction. Not contradiction; but to the neophyte, it appears to be contradiction. Just like we have cited the example that animal stool is impure, but cow dung is pure. So by logic you can say that, "Cow dung is also the stool of an animal. How it becomes pure?" But in Vedas you'll find such things.
Therefore by simple studying, without surrendering yourself to the spiritual master, you'll find all these contradiction and you'll be bewildered. Śrutayo vibhinnā. They are not vibhinnā, but to our limited knowledge, sometimes they appear as vibhinnam, different. Śrutayo vibhinnaṁ nāsau munir yasya mataṁ na bhinnam. And you won't find a philosopher who does not agree . . . who does not disagree with other philosophers.
Therefore dharmasya tattvaṁ nihitaṁ guhāyāṁ mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). We have to follow the footsteps of great ācāryas. That is the way. These mahājanas are described in the śāstra like Lords Brahmā, Lord Śiva, svayambhūr nāradaḥ śambhuḥ kapilaḥ kumāro manuḥ (SB 6.3.20). They are all mentioned.
So you follow any one of these great personalities. Brahmā . . . Brahmā is the greatest personality within this universe, and he has got his sampradāya, which is known as Brahmā-sampradāya. Similarly, Lord Śiva has also a sampradāya, which is called Rudra-sampradāya. Similarly, Nārada-Pañcarātra, Kumāra-sampradāya. So follow the sampradāya. Sampradāya vihīnā te mantrās te viphalaṁ matāḥ (Padma Purāṇa). If you do not follow any bona fide sampradāya, then your path of spiritual advancement will be baffled. You will simply waste your time. Viphalaṁ matāḥ. So we should follow the footsteps of great ācāryas. Then our progress is positive. There is no fear.
So to take shelter of the lotus feet of the Supreme Personality of Godhead . . . just like Rūpa Gosvāmī's described . . . describing herewith that he wants to take shelter of the ocean, deep into the ocean, and he doesn't care for the river. And the . . . what is called? Bharavagni ? There is some whirling pool in the water. That is compared with the arguments. Sometimes these logicians, they create argumental calamity in the process of devotional service.
But Rūpa Gosvāmī recommends that we should not be deviated by the arguments, karmīs, jñānīs and yogīs. Let them do their own business. We do not care for them. We give them respect as far as possible, but we don't . . . don't accept the path of karma-jñāna-yoga. Jñāna-karmādy-anāvṛtam (CC Madhya 19.167).
