If all sects and linguistic/ethnic groups of Jain community follow a specific custom or tradition, we can surely say that is a Jain tradition. On the other hand, if a custom or tradition occurs only in a specific group of the Jain community, it is not a Jain tradition.
To explain more, I would like to give an example. All Sects, linguistic and ethnic groups of Jain community, follow vegetarianism. So vegetarianism is a universal custom followed by all Jains. But if a specific group of Jains does not eat groundnuts, we cannot say that Jains do not eat groundnuts.
I have seen many rural Jains from South Maharashtra and North Karanataka who think that speaking Kannada is a must thing for being a Jain. If you are a Jain but cannot speak Kannada, you are not a Jain for them.
In my high school days, when I told to a Marwadi Jain classmate that I am also a Jain, he started to speak in Marwadi language. But as I didn’t know this language, he was surprised and asked, “ No, you are not a Jain, you cannot speak Marwadi”
So presenting languages, customs and traditions of a small part of entire Jain community as Jain things is just a stupidity. This happens just because most of the Jains know nothing about the Jains not belonging to their own caste, sect and linguistic & regional groups. There is a big communication gap between various types of Jains.
Every group is living like frogs in a pond. For them, their group is the only or the true Jain group.
Here are some statements always presented as Universal things about Jain community:
● Jain monks are naked
● Jain monks wear a piece of white cloth on their mouth
● Jains speak Gujarati language
● Jains speak Marwadi language
● Jains speak Kannada language
● Jains do not eat root vegetables
● Jains do not eat Potatoes
● Jains do not eat Onions
● Jains do not eat Garlic
● Jains worship idols
● Jains do not worship idols
● Jains are rich people
● Jains are from Rajsthan
● Jains are from Gujarat
● Jain community is a merchant community
● Jains do not join armed forces
● Jains avoid agriculture
All the above statements are partial truths and not the whole truths. Those who think any of above statement as a whole truth, is just like the blind person in the story of the Elephant and Five Blinds.
