It is not Brahminism that ruined our society. Those Ambedkar and Periyar followers are wrong. Brahmins are just like any other caste. Like Dalits.
All of them need some sort of identification so they can get a feeling that they belong to a certain group.
This tendency is there in animals & birds too. That is why you see animals in groups. Then there are sub groups. Dogs of a locality have their territories marked. They won't let in dogs from outside into the territory, unless the newcomer is holding its tail down, ready to serve the authoritian Jdogs of that territory.
When Lord Krishna spoke, He spoke of Varnas and not Castes. Now, Varnas are different. They are decided based on the type of work a person does.
A king is a kshatriya. A teacher is brahmin. A businessman is vaishya. Someone doing things like cleaning up is shudra.
Lord Krishna never spoke of untouchability when explaining varna system. He said people were recognized and got a place in society (varna system) according to the work they did. There was no untouchability back then.
I do not know when and how the varna system turned into caste system to ruin the loves of many. Unlike varna system, where people where assigned a status according to their work, caste system labels people by their birth into families that have already been categorized...(probably from leftovers of varna system).
So if a person is born into a shudra family, but by karma, achieves good knowledge and humility, he will still be branded a shudra whereas the varna system would have placed him as a brahmin.
The transformation of varna system into a rigid caste system has ruined many lives. People without talent are ruling while people with knowledge are sweeping roads.
I will not talk of government provided reservation system in this post. But I'd want to say such a reservation system increases the rigidity of castes, making it impossible to eradicate the feeling of superiority.
The feeling of superiority is what I think might have led to the rigid mindset of caste system. Our vedas don't mention caste system. They are liars who say Manu propagated caste system. They were all talking about varna system where people could go to higher castes utilizing their karma/work/knowledge.
It is now almost impossible to shed off the rigid caste mindset. The feeling of superiority is all prevalent. It suppresses lower castes and stops them from progressing. If they want a decent life, they have no choice except to leave India.
Though Ambedkar asked people to take up Buddhism, it won't change your identity in people around you. If you were a Dalit who converted to any religion, you are still a Dalit for people around you. That's why we have Dalit Christians and Dalit Muslims in India. You wont find them anywhere else in the world.
Let's come back to the feeling of superiority. People taking birth into higher castes are considered better no matter how dirty they are. Walk into the house of any upper caste person, and most of the time you'll sure encounter stink. Being born in upper castes doesn't instill cleanliness automatically - material or spiritual. Neither does being born into a lower caste make anyone dirty by default.
In my opinion, clarity of soul matters more than caste. Bodies are just instruments (कारक: neither कर्म, nor कर्ता). Bodies are not reflections of soul. They are mere instruments that help you polish your soul.
No need to feel disgusting if anyone is born into a lower caste. They can still polish their souls. No need to carry superiority when born into a higher caste. Such an attitude may degenerate your divine qualities.
Caste system is a myth. Castes were never declared by Lord Krishna or even Manu. Somewhere between Lord Krishna and Gandhi, somebody turned off varna system to gain and retain that superiority feeling.
In that feeling of superiority, the pride of your caste, you are ruining the whole lives of your children, the coming generation. I won't talk about politics on caste. We all know it's dirty talk. So when you know politicians are wrong, when will you be correcting your mindset to let your children be what they want? To let them get what they want? There's more to say - your three month old kid is actually many thousand years old atma (soul). Ever thought that way?!
