And how we can understand the representative of Kṛṣṇa? That is not very difficult. Because what Kṛṣṇa says, if the representative says the same thing, then he's representative. It is not very difficult. Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). If His representative says that, "You surrender to Kṛṣṇa," he's representative. That's all. He does not become, himself, Kṛṣṇa. Then he's bogus. A faithful servant will never say that, "I am the master." "I am servant"—although he's as good as the master. Similarly, a guru is sākṣād dharitvena samasta-śāstrair uktas tathā bhāvyata eva, kintu prabhor yaḥ priya eva tasya. He, he is the most confidential, dear servant of Kṛṣṇa. That is guru. That's all. He does not know anything but Kṛṣṇa.
Just like Caitanya Mahāprabhu presenting Himself: gopī-bhartuḥ pada-kamalayoḥ dāsa-dāsa-dāsānudāsaḥ (CC Madhya 13.80). A guru is always the servant of the servant of the servant of the servant of Kṛṣṇa. He does not represent himself direct servant. How he can be direct servant? But if you are in the disciplic succession of the servitude, servant of the servant of the servant, evaṁ paramparā-prāptam (BG 4.2), then you become representative. And there is no difference between the original guru, Kṛṣṇa, and the latest guru Kṛṣṇa. Because the aim is the same. Kṛṣṇa personally says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66).And who is representative of Kṛṣṇa, he'll say the same thing: "You surrender to Kṛṣṇa." Kṛṣṇa says, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). The guru will say, "Yes, you become always Kṛṣṇa conscious." Man-manā. Kṛṣṇa says man-manā. A guru says, "You become Kṛṣṇa conscious." The same thing. There is no difference. You become devotee of Kṛṣṇa. You always think of Kṛṣṇa. You always chant of Kṛṣṇa. You always speak of Kṛṣṇa. You do not know anything but Kṛṣṇa. Simply this life is required.
