So simply by carrying these words that, "Kṛṣṇa is the Supreme Personality of Godhead. He wants that you surrender unto Him."
So any child can carry these words. Any foolish man can carry these words. And if you do that, Caitanya Mahāprabhu says, then you become guru, simply by carrying these words. Āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128). Even in your village, in your home, you can say to your wife, to your children. They will accept you that, "Kṛṣṇa is the Supreme Personality of Godhead." Then you become guru at home. Where is the difficulty? Is there any difficulty? But people will not do that. This truth they will not say. What is the reason? Say what is the reason why they do not carry this message, simply to say everyone, whomever you meet. You are meeting daily with your wife, to your children, your friends. If you simply do this missionary work and say that, "Kṛṣṇa is the Supreme Personality," then you become a great devotee. You become a guru. Why people do not do so? It is not very difficult task. This is Caitanya Mahāprabhu's mission. He said that, "By My order you become a guru." Indians especially are advised to become guru because Indians, however fallen they may be, they still have respect for Kṛṣṇa. Every home, they perform Kṛṣṇa's Janmāṣṭamī.
So therefore Indians are fortunate. They recognize Kṛṣṇa. Now, to become little more advanced, let them act as Kṛṣṇa's servant. Kṛṣṇa came to speak this truth that, "I am the Supreme." Mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7). Sarva-dharmān parityajya mām ekaṁ śaraṇam (BG 18.66). He appeared to speak this philosophy. And if you do the same work that, "Kṛṣṇa is the Supreme Personality of Godhead," then you are serving the mission of Kṛṣṇa, great service to Kṛṣṇa. The words for which He appeared on this earth, if you simply carry these words door to door, village to village, man to man, then you become a guru, a real guru. Not to pose yourself a guru without any knowledge of Kṛṣṇa. That is cheating.
