Mahā-prasādam is nondifferent from Kṛṣṇa. Therefore, instead of eating mahā-prasādam, one should honor it. It is said here, karilā vandana, "he offered prayers." When taking mahā-prasādam, one should not consider the food ordinary preparations. Prasāda means favor. One should consider mahā-prasādam a favor of Kṛṣṇa. As stated by Śrīla Bhaktivinoda Ṭhākura, kṛṣṇa baḍa dayāmaya karibāre jihvā jaya svaprasāda-anna dilā bhāi. Kṛṣṇa is very kind. In this material world we are all very much attached to tasting various types of food. Therefore, Kṛṣṇa eats many nice varieties of food and offers the food back to the devotees, so that not only are one's demands for various tastes satisfied, but by eating prasādam one makes advancement in spiritual life. Therefore, we should never consider ordinary food on an equal level with mahā-prasādam.
(Sri Caitanya Caritamrta----3:11:20----purport).

We have to accept the path of great personalities. Otherwise, if we want to understand the Absolute Truth simply by arguments and logic, oh it will never be achieved.
athāpi te deva padāmbuja-dvaya-
prasāda-leśānugṛhīta eva hi
jānāti tattvaṁ bhagavan-mahimno
na cānya eko 'pi ciraṁ vicinvan
(S.B.10;14;29)
The path of spiritual realization is for him who has a slight mercy of the Supreme Personality of Godhead. Athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta. Prasāda means mercy; leśa, a slight. If one has achieved a slight benediction of the Supreme Personality of Godhead, he can understand what he is. Na cānya eko 'pi. And others, eko 'pi. Those who have not achieved that causeless mercy, na cānya eko...ciraṁ vicinvan. For lives together, if they go on contemplating and meditating and speculating, it is not possible. It is not possible.
(Lecture on Bhagavad-Gita----8:5).

There are many more times living entities in the spiritual world than in this material world. In the material world we see so many living entities, conditioned, 8,400,000 species, and in each species, millions and millions are... And there are millions and millions of planets and universes. All these taken together, they are conditioned soul. Similarly, many more times... This is called one-fourth creation, and the three-fourth creation is the spiritual world. Just imagine how many living entities are there. They're all mukta. They're liberated. Because they do not think that "I am enjoyer." Kṛṣṇa is only enjoyer. Here everyone is thinking that "I am enjoyer." I am enjoyer, therefore fight. You are enjoyer, I am enjoyer. So you are enjoying most... "Oh, you have taken more food." Just like cats and dogs, they fight. Because the disease is that "I am enjoyer." Prasāda means that whatever by the mercy of Kṛṣṇa I get, that is called prasāda. And when we fight, oh that is not prasāda. Then immediately it becomes ordinary ḍāl wal.(?) So this is the center of devotion, that Kṛṣṇa is enjoyer. And as soon as we think that "Why Kṛṣṇa should be enjoyer alone? I am also enjoyer," that is māyā.
(Lecture on Srimad Bhagavatam----1:2:6).

Those who are conditioned, they cannot understand Kṛṣṇa. They will say, "Kṛṣṇa (is) dark," "Kṛṣṇa is unknown." "Kṛṣṇa is black." That's all. Because he is seeing with his eyes. Kṛṣṇa is not unknown. Kṛṣṇa (is) known only to the devotees. Athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta eva hi jānāti tattvam (S.B.10:14:29). Athāpi te deva. "My dear Lord, by your mercy one who has got a little, fragmental portion of your mercy," prasāda leśa. Prasāda means mercy, and leśa means very small portion. "Anyone who has got a little portion of your mercy, he can know you." Athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta eva hi jānāti tattvam, he can understand. Na cānya eko 'pi ciraṁ vicinvan. Others, they can go on speculating on their philosophy for millions of years, still they will not be able to understand. They will not be able to understand, simply futile, simply futile, they cannot.
(Lecture on the Nectar of Devotion).

The argument is sometimes offered: "The vegetable has got life." Yes, we admit also. But our process is to take the prasādam.Prasādam means we offer foodstuff to Kṛṣṇa and after eating, whatever He left, we take that. This is our principle. We don't take directly. What is the meaning of this temple? We don't use anything directly unless it is offered to Kṛṣṇa. So the vegetable has got life, but Kṛṣṇa says, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati, tad aham aśnāmi (B.G.9:26). We have invited Kṛṣṇa, Caitanya Mahāprabhu, as our guest, and He has consented to come here. So we must offer foodstuff, what He wants, not that according to my whims. That is not etiquette. If some respectable guest comes to your house, you ask him, "What shall you eat, sir? What kind of food I can give you?" So whatever he orders, you have to supply. That is real receiving the guest. So Kṛṣṇa says that "Give Me food amongst these items-patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati. That also with bhakti, not neglectfully. With great devotion, if somebody offers Me these things, then I can take." So Kṛṣṇa takes these, these patraṁ puṣpaṁ phalaṁ toyaṁ, grains, food grains, and milk and vegetables and fruits. So we prepare hundreds of items with these things. You can do that. And they are all delicious and full of vitamins. So why one should kill unnecessarily the poor animals and become vicious and sinful?
(Sunday feast lecture).

The nature is that everyone should eat another animal or another living creature for existence. That is the law of nature. Jīvo jīvasya jīvanam: "One living entity is the life of another living entity." That is a fact. Just like sahastānām ahastānam. Those who have got hands—that means men—for them, ahastāni, means the animals who have got no hands. And apadānanaṁ catuṣ-padām: "And the four-legged animals, they eat the grass, who cannot move." So grass has got life, as the animal has got life. We have got life. So this is... Nūnaṁ mahatāṁ tatra: "The strong is eating the weak." So this is the law of nature. We are eating the grains and fruits. They have got also life. It is not that those who are vegetarians, or eating grains and fruit, they are not eating life. They are also eating life. But the bhakti-yoga process is that, as it is stated in the Bhagavad-gītā, that the devotees, they take prasādam. We have got arrangement of distributing prasādam in every Sunday. Prasādam means the foodstuff which is offered to Kṛṣṇa and then you take. So what Kṛṣṇa wants, that is also stated in the Bhagavad-gītā, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (B.G.9:26). Therefore we are not propagating the philosophy of ahiṁsā, or nonviolence, because in some way or other, there is violence, either you take fruit or grain or animal. But the principle is that you have to take prasādam, the foodstuff which is offered to Kṛṣṇa, and then eat. So these things, fruits, grains, are accepted by Kṛṣṇa. We offer to Kṛṣṇa and then eat them. This is the philosophy.
(General Lecture).

Sevonmukhe hi jihvādau (Brs. 1.2.234). The controlling of the senses begins from the tongue. If you allow the tongue to eat anything in the restaurant or anywhere, then you cannot become the jitendriya. And if you can control the tongue—"My dear tongue, I shall not give you any food which is not offered to Kṛṣṇa, kṛṣṇa prasādam"—then the tongue is controlled. And kṛṣṇa-prasādam means patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (B.G.9:26). If you want to offer Kṛṣṇa something, we must know what Kṛṣṇa wants to eat. Just like if you call a friend, you ask him, "My dear friend, what do you like to eat?" Then it is etiquette. And that is going on. Similarly, you have invited Kṛṣṇa here. He has come. Don't think He has not come. He is here, sākṣād vrajendra-nandana-hari. The atheist may say, "Oh, these rascals are worshiping a stone," but that is not the fact. We are not spending so much energy and money for installing a stone. Stone is already there. Therefore it is forbidden, arcye śilā-dhīr guruṣu nara-matiḥ. If you think the Deity as śilā, means stone, and guruṣu nara-matiḥ, if you think guru as ordinary human being, vaisnave jati-buddhi, and if you think a Vaiṣṇava, "He is American Vaiṣṇava. He is Indian Vaiṣṇava," jāti-buddhi nārakī—you become nārakī immediately. These are the descriptions.
(Lecture on Srimad Bhagavatam----12:7:6).

You should take prasādam. Kṛṣṇa baṛo doyāmoy, koribāre jihwā jay, swa-prasād-anna dilo bhāi, sei annāmṛta pāo, rādhā-kṛṣṇa-guṇa gāo, preme ḍāko caitanya-nitāi. Kṛṣṇa baṛo doyā... Our tongue is the greatest enemy. Tā 'ra madhye jihwā ati, lobhamoy sudurmati. The tongue is the greatest enemy, and if you can control the tongue, then you can control all the senses. Otherwise tongue will dictate, "Give me this kind of food, give me this kind of food." And if you don't take prasādam in the temple, then our tongue will dictate, "Now you can prepare some nice food. Let us take it." That will not help us in our Kṛṣṇa consciousness. Whatever Kṛṣṇa..., kṛṣṇa baṛo doyāmoy, koribāre jihwā jay. Kṛṣṇa-prasāda means to control the tongue. Our main enemy is the tongue. In another place it is said, sevonmukhe hi jihvādau svayam eva sphuraty adaḥ: (Brs. 1.2.234) "God realization becomes by keeping the tongue engaged in the service of the Lord." Sevonmukhe hi jihvādau. The tongue has to be first of all engaged, not the hands and legs. "I have to serve Kṛṣṇa. So yes, I am ready. I am expanding my hands. I am going there." But śāstra says, "No, no, no. Not your hands and legs but your tongue. This is the one. First of all engage your tongue." This is astonish: "How can I serve with tongue? If I have to serve, I have got my hands and legs, my eyes and I..." No. Śāstra says tongue. This is very peculiar. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. If you engage your tongue... So how to engage my tongue? What is the business of my tongue? Two business only: to taste, or eat, and chant. Chant Hare Kṛṣṇa with tongue and take kṛṣṇa-prasādam—you will conquer Kṛṣṇa. This is the program. Sevonmukhe hi jihvādau. So if you do not control your tongue, if you feel inconvenient in taking prasādam, that means you are not making progress.
(Lecture on Srimad Bhagavatam----6:1:8).
