Dr. Ghosh: Bhakti is in the mind, in the heart.
Prabhupāda: No, not in the mind. No, no. Bhakti is in the heart, but there must be... Just like if you have got love for me in the heart, it must be demonstrated. Just like a husband and wife. The wife says, "Now we are married and I have got love for you. Let me remain here. You go to your home." The bridegroom comes, "Now we are married and I love you, you love me. You go home; I remain here." Is that very good proposal?
Dr. Ghosh: No, but this...
Prabhupāda: This is nonsense. (laughing) "I have got bhakti, but I don't do anything for You. You go home." So that is not bhakti. Bhakti must be exhibited by activity. That is the definition of bhakti. Śravaṇam kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam (SB 7.5.23). So these are the nine different ways of expressing bhakti. First thing is śravaṇam. Śravaṇam. Śravaṇam kīrtanaṁ, chanting and hearing. Of whom? Of Viṣṇu. Śravaṇam kīrtanaṁ viṣṇoḥ. Not of any other one. The Māyāvādī philosophers, they say that "We can chant anyone's name, either I chant of any demigod's name or any name."
Dr. Ghosh: But does He not say that "Whatever or whoever does it, it comes to Me."
Prabhupāda: That is avidhi-pūrvakam. That is said, avidhi-pūrvakam, "Not in order."
ye 'py anya-devatā-bhaktā
te 'pi mām eva kaunteya
('Whatever a man may sacrifice to other gods, O son of Kuntī, is really meant for Me alone, but it is offered without true understanding.')
That is not vidhi. Vidhi is here: śravaṇam kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam. The first word is Viṣṇu, of Viṣṇu, not of any other. So these are the demonstration of bhakti. Śravaṇam kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam arcanaṁ (SB 7.5.23). This is arcanā. Just like we perform in the morning, in the evening, at noon, arcā-vigraha. Viṣṇu-arcayam. Viṣṇu. It is not idol worship. Arcayaṁ viṣṇu-śilā-dhiḥ. If one thinks the arcā-mūrti, the worshipable Deity in the temple, as stone or as wood, arcayaṁ viṣṇu-śilā-dhiḥ guruṣu nara-matiḥ... To accept guru, in the paramparā system... All the gurus in the paramparā system—evaṁ paramparā prāptam (BG 4.2)—nara-matiḥ, considering as ordinary human being... In this way there is a list. Vaiṣṇave jāti-buddhiḥ. A Vaiṣṇava, a devotee: "He is brāhmaṇa Vaiṣṇava," "He is American Vaiṣṇava," "He is śūdra Vaiṣṇava." No. When one is Vaiṣṇava, there should be no distinction by the caste. Vaiṣṇave jāti-buddhiḥ. In this way there is a list that should be avoided.
So these things required. If actually... The same thing, that if a girl is married to the husband, she must be always engaged in the service of the husband. That will be appreciated. If she says, "Sir, now we are married. You go home and I remain at home," there will be no prayojana-siddhi (fulfillment). The real purpose of marriage is to get children. Putrārthe kriyate bhāryā. So if the husband and wife simply love within the mind and there is no action, there is no prayojana-siddhi. We should be practical, not simply theoretical. So love between two persons, there must be exchange of loving feelings. These are the exchange of loving feelings. Unless the exchange loving feelings are there, that is not love. That is theoretical. That is not practical. It is...
I have explained in the beginning of Kṛṣṇa book that love is practical exhibition. It is not theoretical. We cannot keep love within the heart. If actually it is within the heart, it must be expressed practically.
