Anyone who does not understand what is Kṛṣṇa and what is Kṛṣṇa's service, he may be very big man in the ordinary estimation, but we don't give him any value. Harāv abhaktasya kuto mahad-guṇā manorathenāsati dhāvato bahiḥ (SB 5.18.12). Because they are mental speculators. They have no value. They have their value in their own way, but according to our line of thought, they have no value.
So prajalpa . . . in this way, prajalpa, there is tendency of talking. You talk of Kṛṣṇa. That is Kṛṣṇa consciousness. That is Kṛṣṇa consciousness. Just like we assembled together, few friends, (baby cries) we want to vibrate something. Just like the child is also vibrating. That is nature. A bird will vibrate, a beast will vibrate. So we have to vibrate the transcendental sound.
Then we shall be saved from the plundering business of the sun. This is the secret. Always talk of Kṛṣṇa, and you must know that you are saving yourself; you are not dying yourself. Because talking of Kṛṣṇa means you will understand about Kṛṣṇa. And Kṛṣṇa says: "Anyone who understands Me rightly, then after giving up this body, he comes to Me." And as soon as you go to Him, back to home, back to Godhead, your life is eternal, blissful and full of knowledge. That is sac-cid-ānanda-vigraha (Bs. 5.1).
