Mixed smell is sometimes perceived in foodstuffs prepared from various ingredients, such as vegetables mixed with different kinds of spices and asafoetida. Bad odors are perceived in filthy places, good smells are perceived from camphor, menthol and similar other products, pungent smells are perceived from garlic and onions, and acidic smells are perceived from turmeric and similar sour substances. The original aroma is the odor emanating from the earth, and when it is mixed with different substances, this odor appears in different ways.
(Srimad Bhagavatam-----3:26:45-----purport).

Since the child depends completely on the assimilated foodstuff of the mother, during pregnancy there are restrictions on the food taken by the mother. Too much salt, chili, onion and similar food is forbidden for the pregnant mother because the child's body is too delicate and new for him to tolerate such pungent food. Restrictions and precautions to be taken by the pregnant mother, as enunciated in the smṛti scriptures of Vedic literature, are very useful.
(Srimad Bhagavatam-----3:31:5-----purport).

By bhajana-kriyā one attains freedom from the contamination of materialistic life. He no longer goes to a restaurant or hotel to taste so-called palatable dishes made with meat and onions, nor does he care to smoke or drink tea or coffee. He not only refrains from illicit sex, but avoids sex life entirely. Nor is he interested in wasting his time in speculating or gambling.
(Nectar of Instruction).

Just like sometimes our students are perplexed when we say that onion is not to be taken, but onion is a vegetable. So śabda-pramāṇa means the Vedic evidence should be taken in such a way that no argument. There is meaning; there is no contradiction.
(Lecture on Bhagavad-Gita-----2:8-12).

Prabhupāda: We don't eat anything which is not offered to Kṛṣṇa. We first of all prepare foodstuff as recommended in the scripture. They are mostly from vegetable, grains, fruits, milk. So we have got enough food.
Interviewer: No meat of any kind.
Prabhupāda: No. No meat, no onion, no garlic, no intoxication, no liquor, we don't smoke even, we don't take tea, coffee. We simply take what is absolutely necessary for keeping the body fit to execute Kṛṣṇa consciousness. We don't indulge in luxury..., or for the satisfaction of the tongue.
(Room Interview).

Because mushrooms grow in a filthy place, they are not usually offered to Krishna.
(Letter to Himavati).

Nonvegetarian means nirāmiṣa. So āmiṣa and mada and vyavāya. Vyavāya means sex. Loke vyavāya āmiṣa mada-sevā. Sex indulgence and eating meat, flesh, eggs, and drinking wine. Mada. Mada means liquor. Nityasya jantuḥ. Jantu. When one is in the material world he is called jantu. Jantu means animal. Although he's living entity, he's not called jīva soul. He's called jantu. Jantur dehopapattaye. Jantu. This material body is developing for the jantu, animal. Anyone who is devoid of spiritual knowledge, he's called jantu, or animal. This is the shastric injunction.
(Lecture on Bhagavad-Gita-----2:25).

You do not require to encourage them in these things. They have got natural tendency. That is material world—to enjoy unrestricted sex life, to eat meat, fish eggs, āmiṣa... Āmiṣa-madya-sevā. Āmiṣa means eat meat, fish, eggs. These are āmiṣa. And vegetarian means nirāmiṣa. So āmiṣa-madya-sevā. Madhya means intoxication. Either wine or cigarette, biḍi or gāñjā, bhāṅg, teas, coffees, they are all intoxication. So āmiṣa-madya-sevā and vyavāya. Vyavāya means sex life. You do not require to educate them.
(Lecture on Bhagavad-Gita-----7:1).

No meat-eating, no eggs, no fish, no chicken, nothing of the sort. Simply vegetarian. Kṛṣṇa... Not even vegetarian; Kṛṣṇa-prasādam. We don't accept even vegetarian diet. We simply accept Kṛṣṇa-prasādam. So Kṛṣṇa-prasādam which is vegetable. Kṛṣṇa does not eat meat because He says in the Bhagavad-gītā, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (B.G.9:26). Kṛṣṇa says that "Foodstuff prepared from vegetable kingdom, anyone offering Me with devotion and faith, I eat." He says, "I eat." So when Kṛṣṇa says He eats, so you should offer Him such nice prasādam so that He can eat and you take Kṛṣṇa-prasādam. Prasāde sarva-duḥkhānāṁ hānir asyopajāyate. So you take Kṛṣṇa-prasādam.
(Initiation Lecture).

There are six kinds of rasas (tastes), and if one is agitated by any one of them, he becomes controlled by the urges of the tongue. Some persons are attracted to the eating of meat, fish, crabs, eggs and other things produced by semina and blood and eaten in the form of dead bodies. Others are attracted by eating vegetables, creepers, spinach or milk products, but all for the satisfaction of the tongue's demands. Such eating for sense gratification—including the use of extra quantities of spices like chili and tamarind—is to be given up by Kṛṣṇa conscious persons. The use of pan, haritakī, betel nuts, various spices used in pan-making, tobacco, LSD, marijuana, opium, liquor, coffee and tea is indulged in to fulfill illicit demands.
(Nectar of Instruction).

Those outside of the Kṛṣṇa consciousness movement are interested in reading heaps of newspapers, magazines and novels, solving crossword puzzles and doing many other nonsensical things. In this fashion people simply waste their valuable time and energy. In the Western countries old men, retired from active life, play cards, fish, watch television and debate about useless socio-political schemes. All these and other frivolous activities are included in the prajalpa category. Intelligent persons interested in Kṛṣṇa consciousness should never take part in such activities.
(Nectar of Instruction).

Modern administrators want to banish corruption from the state, but fools as they are, they do not know how to do it. They want to issue licenses for gambling houses, wine and other intoxicating drug houses, brothels, hotel prostitution and cinema houses, and falsity in every dealing, even in their own, and they want at the same time to drive out corruption from the state.
(Srimad Bhagavatam-----1:17:43-44-----purport).
