Entry to temple after eating non-vegetarian food

Ultimately, isn't one's faith that matters? How does what one eats, determine whether or not it is ok to enter a place of worship? Does God judge the person who enters? I think not!

As for having a bath, I think this is something most people do as a sort of conscious decision of maintaining cleanliness before entering a place of worship, but this, again, should not be something that should prey on one's mind.

During the evolution of the human species on earth the humans mainly survived on animal meat and fruits and eatable shrubs available at that time in the jungles. So in the beginning there was no concept like vegetarian or non vegetarian. It was only after the development of various civilizations across the world that people started to have a concept of God and that was the starting point of various religions coming in picture. Gradually every religion started to have its own guidelines and policies in the matter of religion which most of the people followed and that was the basic premises on which major religions developed across the globe.
Some religions linked food habits to the religious practices while others did not. Some religions worshipped in groups while others advocated for individual worshipping. There were so many differences between the religions across the world that people started to antagonise with each other just based on their religions.
The rituals and customs of one religion sometimes differed with one another significantly.
In Hindu religion there is emphasis on eating vegetables and milk derived items. Killing of animals is not recommended in Hindu religion. Eating meat is also considered as a demonic activity and not viewed as a good choice for food. That is the reason why some people do not like to visit religious places on the days they have consumed non vegetarian items.
So it is only a matter of faith and belief that people have apprehensions like that.
In essence people follow what they feel correct as per their family background and upbringing collectively called 'Sanskars'.
So entering the temple after taking non vegetarian food is only a matter of one's faith and belief and one has to follow that.

In what way you would like to offer prayers varies from person to person. It is a matter of belief and sentiment. In our society, many people offer prayers after having breakfast. They have faith on God and they don't connect with food items whether they eat veg or non-veg. It is true that eating non veg item has been prohibited in hindu culture. Many people don't want to go temple when they have non- veg item. But people were more sentimental in earlier times. Now people are being advance day by day. And it completely depends on person either he/ she are pious in nature or not because it is a matter of faith. It is subject of family background also. That means in which environment you were born and brought up. In my family since childhood all members used to have breakfast after having bath and offering prayers. Without having bath, they won't allow to have breakfast. Actually, we were complete 'vaishnav'. Whereas, our in-laws used to have breakfast then go for bath. They are non-veg eaters. So, it is person's own choice.

It is a matter of faith and perception one keeps about cleanness. and hygiene.

We have to keep hygiene and 'cleanliness' in and around us. That is termed as "Baahya-Abhyantarah- Shuchi "-which means cleanliness of external and internal.
However, here 'internal' cleanliness mainly attributes to 'cleanliness of our mind i.e thoughts.
But our simple basic(wrong) assumption is that internal means only our internal organs.

It is believed and known that certain types of food give certain type of results or Gunas. It is understood that a person becomes internally and externally at peace and bliss when he is having mainly the "Satva Guna". "Satvic" food gives Satva Guna mostly.
Non-Veg food is not one among Satvic foods. It is believed that Thamo and Rajo Guna foods(non-satvik) can increase the negativity in a person. That is probably why people avoid non-veg foods before going to any holy places, especially temples. People go to temples to have mental peace and positive bliss.

However if one is a non-veg consumer generally and does not feel guilty to be so, one may go to temples as far as he is keeping self hygiene and does not cause harm to the general hygiene of the place and people.

Whether Veg or non-veg or any other thing one consumed, one should ensure that he does not dirty the holy places by spit, vomit, etc.

That all depends on the beliefs and faiths of the individual.
Many people believe that one should go to the temple before eating food. Some advocate that it is better to go after eating only as people can concentrate more on God rather than hunger. But it is better to have a bath before going to the temple. This is to maintain cleanliness. Nothing wrong if you go to a temple after eating veg or nonveg food. But take a bath and wear fresh clothes and then go to the temple. So that the sanctity of the temple can be maintained.
If we go to the temple with an empty stomach we will be hungry and we want t finish the rituals so we come back and eat, Instead of that if we go after eating we can concentrate more and spend some time peacefully without any disturbance.
So personally I feel when you go is not important but how religious you are is more important. We should be able to sit calmly and meditate and pray God dor sometime with focus and concentration.

I don't think that any correlation exists between our taking veg Or nonveg foods while going to temples for showing our respect to God and Goddess. It is our mental state of affairs how best we are deeply attached with the emotions of attachments. If we have the deepest faith with our Hindu Religion having regards for our devis and devatas but before entering the temples having taken nonveg tab is not likely to impact our degree of attachments for our God or Goddess. It is immaterial of the varieties of foods. However. We should take care of surroundings maintaining decencies in our behaviours in the temples.

The thing is how come one limits the existence of a God to within the boundary wall of a temple? If one believes Him to be everywhere then follow suit everywhere.

In addition, why do we feel that few animals are just there to get slaughtered, cooked, and then eaten by us? Few will come up with a few silly answers like if we do not eat them their numbers will increase creating a burden on the resources. I do not know then why this does not happen to other creatures who are not thought to be created to be eaten by us. By the way, do not feel that God can be befooled that what you do outside the temple will not be in his conscious.

It is argued in many temples itself non vegetarian foods are got cooked and served and we get stories that devotees offered non vegetarian foods to God. But non vegetarian foods are normally considered as left items for the ethics. Being an eater of non vegetarian foods one could fail to get a Saadvik Guna in him or her. Our mind will also get polluted and enter into the impurified level once we eat non vegetarian foods and the mind also addicted to the second thoughts. It is said, for this, all virat dins one should not consume non vegetarian foods. If one go to temples after eating non vegetarian foods he or she definitely creates problem there by shouting or fighting or arguing instead of seeking darshan peacefully with patience. This is because of his 'rajas, thaamas Gunas are over occupy him or her without keeping him or her patience.
