Guru Does Not Change Krishna's Words - Prabhupada 0215

If Kṛṣṇa sees that, "One is presenting My message as I have given," then He is pleased. Therefore it is said, kintu prabhor yaḥ priya eva tasya. He has become very dear because he do not nonsensically change the meaning that, ""This meaning's that, this meaning's that."" Why? When Kṛṣṇa has said, that is everything perfect. Why should I change it? That is guru-priya.
Suppose if you say something and if somebody takes it as it is and behaves like that, then you become pleased. And if you say to your son or to your servant something and he misunderstand and talks something else, then he becomes angry, ""What this nonsense has understood?"" Similarly, a guru does not change the word of Kṛṣṇa. Therefore he's called Bhagavān, servant Bhagavān. Kṛṣṇa is the master Bhagavān, master God, and the guru, who is serving Kṛṣṇa sincerely, he's the servant God.
