So ceto-darpaṇa-mārjanam (CC Antya 20.12) means you'll be get. . . you'll be freed from this ignorance that "I am something of this material world." This is wanted. So long we are not realized, self-realized, then we are no better than these cats and dogs, because they do not know that he is not the body. So if we think that "I am this body," then we are no better than the cats and dogs. So if you want to become happy, first of all we must get this knowledge, that "I am not this body." Now we are busy with the bodily demands of life. We are not busy for spiritual demand of life. That is the business of the human being, that "I am not this material body. I am spirit soul. So my business is different from the business at the present moment we are engaged in." Everyone is engaged for satisfying the bodily necessities of life. Everyone. The cats and dogs, animals, they are also busy how to fulfill the demands of the body. The demands of the body are four: āhāra-nidrā-bhaya-maithunaṁ ca (Hitopadeśa). Āhāra means eating, and nidrā. . . Nidrā means sleeping, āhāra-nidrā-bhaya. Bhaya means to become fearful, to become anxious, full of anxieties. Āhāra-nidrā-bhaya. And maithuna, and sexual intercourse. So these are the demands of the body. They are called viṣaya. Viṣaya means so-called enjoyable, viṣaya. But the Vaiṣṇava says that viṣaya chāḍiyā, se rase majiyā, mukhe bolo hari hari. The transcendental sound Hari, Hare Kṛṣṇa, should be chanted, viṣaya chāḍiyā, without any attraction for this viṣaya. Āhāra-nidrā-bhaya-maithunaṁ ca. Then it will be perfect.
Nidrāhāra-vihārakādi-vijitau cātyanta-dīnau ca yau (Sad-gosvamy-astaka 6). The Gosvāmīs, they conquered over these things. Nidrāhāra-vihāra. That is required. That is spiritual life. If you are embarrassed with these four things, āhāra-nidrā-bhaya-maithunaṁ ca, then we are not making progress in spiritual life. It should be reduced, just like Raghunātha dāsa Gosvāmī did—all the Gosvāmīs. They had no business. But that is very difficult. If one has to imitate the behavior of Rūpa Gosvāmī and all the Gosvāmīs, it is very difficult. Therefore yukta-vairāgya. We must eat kṛṣṇa-prasādam as much as it is needed for maintaining my body. Āhāra-nidrā-bhaya-mai. . . In this way, spiritual progress of life. . . But it will be very easy if we chant this transcendental vibration, Hare Kṛṣṇa mantra, offenselessly, niraparādhe. Then immediately you become advanced. Not only advanced; actually spiritual situated.
So the sound is very important thing. The sound is the cause of our bondage in this material world. Just like in big, big cities they are attached to the sound vibrated by the cinema artist. And not only that; so many other things we are hearing through the radio message, attachment for the sound. And because it is material sound, we are becoming materially entangled, entangled more and more. Some actress, some cinema artist, singing, and people are so fond of hearing that singing that the artist is paid fifteen thousand rupees for one song. There are many here in Bombay. So just see how much attraction we have got for the material sound vibration. Similarly, the same attachment, if we turn to hear about Hare Kṛṣṇa mahā-mantra, then we become liberated. The same sound. One is material; one is spiritual. So you practice to be attached by this spiritual sound vibration, then your life will be successful.
