Suppose if I say, “You have no eyes. You are blind,” this is not favorable. The nondevotees, Mayavadis, say that God has no eyes. So it is indirectly saying, “God is blind.” If I say, “You are blind. You nonsense, you are blind,” is it favorably talking? Most unfavorable. Directly insulting. So those who are talking about God, nirakara — no eyes, no leg, no head, no tail, nothing, nirakara — they are simply blaspheming, not sprhaniyam. God does not want to hear such nonsense things. Therefore it is said, sakam vacam sprhaniyam vadanti. You cannot say that “Krsna is blind. Krsna is lame. Krsna has no hands. Krsna has no nothing, nothing,” indirectly saying, “Krsna does not exist.” This kind of addressing Krsna, nirakara, is not favorable talking with Krsna.

Favorable talking — if you want to talk with Krsna, then you must consult the Vedic literature how Krsna is worshiped.
