You are servant of God, that is your position. That is real jñāna. Therefore Kṛṣṇa Caitanya Mahāprabhu says that don't talk all nonsense thing. Simply say the real thing.
And what is the real thing? That is explained by Kṛṣṇa: sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). You take this mission, "My dear sir, you give up everything nonsense. You simply surrender to Kṛṣṇa." Then you become guru. Is it very difficult to become guru? No. But we shall not take this business. We shall talk all nonsense and become guru and incarnation and God and so on, so on, and cheat others and cheat oneself. This is going on. Otherwise, to become guru is not at all difficult. Simply you surrender yourself to Kṛṣṇa. You become abhayaṁ sattva-śuddhiḥ. You become fearless, "Yes, I am now under the protection of Kṛṣṇa. I have no more fear. I don't care for anyone. I simply take to Kṛṣṇa."
