So Kṛṣṇa has said, "Surrender unto Me," I say "You surrender to Kṛṣṇa," I become guru. Even though I am a fool number one, I become guru, because I am repeating what Kṛṣṇa has said. That's all. I don't require any education. Very simple thing. Everyone can become guru if he simply repeats what Kṛṣṇa has said, that's all.
Repeat what K???a has said, that’s all.
