Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66), and these rascals say, "It is not to Kṛṣṇa person." So he's a rascal. He's taking Kṛṣṇa's book and preaching against it. So what will be benefit if you go to such a rascal? Therefore there is no difference between śikṣā-guru and dīkṣā-guru, because if he's actually guru, he'll not say anything which Kṛṣṇa has not spoken. Yāre dekha tāre kaha 'kṛṣṇa'-upadeśa. So guru is that. Caitanya Mahāprabhu says, āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128): "You become a guru." And what is the function of the guru? Yāre dekha tāre kaha 'kṛṣṇa'-upadeśa. That is there. You haven't got to manufacture any instruction. Whatever is said in the Bhagavad-gītā, you say. You try to convince him with logic, with philosophy, with your knowledge, same thing, not philosophy. That is intelligence. And suppose Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). Before that, Kṛṣṇa has described everything, why you should surrender to Kṛṣṇa. At last He says, "Surrender." So there is no difficulty. Immediately Kṛṣṇa does not say, "You surrender to Me." But after describing everything—karma-yoga, jñāna-yoga, dhyāna-yoga, so many things, politics, sociology, religion, everything—at last He says that "This is the most confidential part. You surrender unto Me."
So one who has not surrendered to Kṛṣṇa, how he can become guru? He's a cheater. Yei kṛṣṇa-tattva-vettā sei guru haya (CC Madhya 8.128). Bahūnāṁ janmanām ante jñānavān māṁ prapadyate (BG 7.19). One who has surrendered to Kṛṣṇa, he's actually jñānavān. And this jñānavān is possible after many, many births. Not so easily, to surrender to Kṛṣṇa. But if he's there, such a person—vāsudevaḥ sarvam iti sa mahātmā sudurlabhaḥ—he is mahātmā. That is mahātmā, not by stamping, anyone, a person can become mahātmā. This is the symptom of mahātmā: one who has surrendered to Kṛṣṇa fully. Sa mahātmā sudurlabhaḥ. So that is guru, mahātmā, who knows vāsudevaḥ sarvam iti. Such mahātmā is guru. Mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ, bhajanty ananya-manasaḥ (BG 9.13). The guru has no other business than kṛṣṇa-bhajana. So that you have to see. You have to learn. You have to appreciate with persons who are actually engaged in kṛṣṇa-bhajana. Then you'll understand. Ādau śraddhā tataḥ sādhu-saṅgaḥ (CC Madhya 23.14). Sādhu means bhajate mām ananya-bhāk sādhur eva sa mantavyaḥ (BG 9.30). He's sādhu. Who? Who has no other business than Kṛṣṇa. Mix with such sādhu who are actually executing kṛṣṇa-bhajana. Ādau śraddhā tataḥ sādhu-saṅgaḥ. This is the description of the sādhu. Bhajate mām ananya-bhāk sādhur eva sa mantavyaḥ. These things are there. There is no question of being misled. But if you purposefully mislead yourself, who can check? In the beginning you may commit some mistake, but when you study Bhagavad-gītā—who is sādhu, who is mahātmā, who is guru—then why shall we make, commit mistake again? If you have done mistake—you have gone to a rascal who is not Kṛṣṇa conscious—then when you read Bhagavad-gītā, you can understand. Why you are misled? Why you should be misled? If it is written on the road, "Keep to the left," why should you be misled and go to the right? Go to the left; then you are not misled.
