This is real friendship. He does not take himself. He always carries the message only. Ya idaṁ . . . mad-bhakteṣv abhidhāsyati (BG 18.68). Simply our business is to carry the message of Kṛṣṇa. Then we are friend. Otherwise we are not friend. We may pose to become friend, but we are not friend, because we do not know how to benefit the friend. Sometimes we mislead him.
Therefore our business is to point out that, "Kṛṣṇa is your friend." Suhṛdaṁ sarva-bhūtānām (BG 5.29). "He's the proprietor. Don't claim your proprietorship. You are not proprietor. You are falsely claiming, because what you are claiming as your property, it will be taken away by Kṛṣṇa at the time of your death. Everything will be finished." Mṛtyuḥ sarva-haraś ca aham (BG 10.34), Kṛṣṇa says. Mṛtyu . . . Kṛṣṇa says: "I am death when I take away everything from the person—his life, property, body and everything."
Actually, we claim, "This is my property." This is moha. Ahaṁ mameti (SB 5.5.8). Lokasya janasya moho 'yam. This is friendship, to educate people that, "You are not proprietor. Kṛṣṇa is proprietor. You are not enjoyer. Kṛṣṇa is enjoyer. You are seeking out friends to give you protection. Kṛṣṇa is the supreme friend who will give you protection." If we spread this message all over the world, then I am friend of Kṛṣṇa and friend of the person. Otherwise, I am not friend.
Because I cannot become friend. I can simply carry . . . just like post peon gives you five thousand rupees, delivers. He does not deliver; somebody else is delivering. He's simply carrying. That's all. Similarly, if we simply carry the message of Kṛṣṇa as it is, we become perfect. It is not very difficult. If I simply carry the message of Kṛṣṇa, where is the difficulty? Everything is there. Kṛṣṇa has said everything. Kṛṣṇa says, man-manā mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). We carry this message. Just always think of Kṛṣṇa, always offer obeisances to Kṛṣṇa, become a devotee of Kṛṣṇa. Man-manā, think of Kṛṣṇa always. We have to carry this message. Where is the difficulty?
So to become a bona fide spiritual master there is no difficulty, simply if we carry the message of Kṛṣṇa as it is, without any adulteration. So we must find out a person who is actually bona fide spiritual master by this test, that he's not, I mean to say, adulterating Kṛṣṇa's message. He's not playing havoc with the message of Kṛṣṇa in order to introduce himself, his person. He's simply presenting the message of Kṛṣṇa as it is. Then he's spiritual master. Nobody else.
