Madhudviṣa: Sometimes a question is arisen that devotees are working hard to serve Kṛṣṇa, but sometimes they don't feel that they are working in love and devotion. They are doing the work, but sometimes . . .
Prabhupāda: Yes, in the beginning there is no love. Let him work on the direction of God's representative. (break) Therefore it has been warned, arcye viṣṇau śilā-dhīr guruṣu nara-matir vaiṣṇave jāti-buddhiḥ (Padma Purāṇa). The Deity of Viṣṇu, if one thinks, "This is made of stone; this is made of wood, this is made of metal," and spiritual master as ordinary human being, these are hellish consideration. Arcye viṣṇau śilā-dhīr guruṣu nara-matiḥ. Guruṣu means the spiritual master; nara-matiḥ, a ordinary human being. And vaiṣṇave jāti-buddhiḥ. And Vaiṣṇava, a devotee—"Oh, he is brahmin Vaiṣṇava. He is European Vaiṣṇava. He is this Vaiṣṇava, that . . ." No. These are forbidden.
Vaiṣṇava is Vaiṣṇava. Spiritual master . . . they are all transcendental. In . . . of course, in this country you are introducing new, but in India . . . just like we had been at Tirupati, Tirumala. Many thousands of people were coming, and their daily collection is not less than 100,000 rupees. And do you think these people are coming to offer these 100,000 rupees daily to a stone? And the ācāryas established this temple for bluffing these people? Does it mean, their collecting? They do not know the science, rascals. And therefore simply . . .
Sinful life cannot help. Vinā paśughnāt (SB 10.1.4). That is stated in the Śrīmad-Bhāgavatam that, "One who is killer of animal, he cannot understand the spiritual science." Vinā paśughnāt. This is the statement. Paśughna means the animal killer. Therefore the first prohibition is, "Stop this animal killing." Otherwise, this dull brain will not be able to understand. They are not fit for understanding. Mūḍha. Mūḍha. Na māṁ duṣkṛtino mūḍhāḥ (BG 7.15). Duṣkṛtina means always engaged in sinful activities. They have got brain, but their brain is being utilized only for sinful activities, they are called duṣkṛtina. Kṛtī, kṛtī means good brain, and duṣkṛtī means brain is being utilized for sinful act. Therefore they are mūḍha. In spite of good brain, they are rascal, because brain is being utilized for sinful activities, how to set up up-to-date machinery for killing animals. Brain is being used for this purpose. Any animal can be killed with ordinary knife, but they're manufacturing latest machinery. Their brain, rascal brain, is being used for that purpose. And what they will understand? They are preparing their road for going to hell. What they will understand about spiritual matters? Nature will not excuse. That is not possible.
