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.
