Your definition of caste from what I could see is birth based only. Perhaps my poor understanding but I have met a large number of birth based Brahmins whose character is very poor. In real world one does run into making this choice when character is not present in the person of your caste.
Dear TKS ji,
I feel you have a problem accepting the fact that caste is birth based.
It has been birth based ever since and it will be birth based till one decides to go beyond caste.
As a Non Brahmin I have totally no problems accepting that caste is birth based.
Most Non Brahmins get angry with the caste being a birth base cos you see each human wants some amount of "superiority" in their life.
People mistake being Brahmin as a feeling of Superiority and that is where all the problem starts!
Many want this caste system to be an open system where anyone can be a Brahmin but yet these same people wont like the idea of anyone else becoming their caste..do you really think a Vaisya or a Kshatriya would like the idea of someone becoming their caste and say its not birth based?
I can safely bet no!
You see let anything be birth based and it should not matter to those who do not subscribe to it.
I have no problems if caste is birth based cos I do not aspire to be in any of the Varnas becos for practical reasons its outdated in my opinion.
The word Guna Brahmin is just some nonsense if you ask me...its just to justify that if someone else besides a Brahmin has good qualities..it is becos by either hook or crook he acquired some Brahmin mindset.
The famous Satyakama son of Jabala is the best example..it only reinforced the fact that only a Brahmin could speak the truth...failing to address the issue that the father of Sathyakama did not even marry his mother and she didnt even know his name..so it was just an exploitation of the one night stand kind...since she was helpless and worked as a maid in some house.
So tell me would a true Brahmin do such stuff..to have a one night stand of this kind?
But still story makes it sound that only Brahmins speak the truth.
The human mind usually has to "personalize" another to feel comfortable..a person who truly respects himself and others would not give anyone caste based tags and accept the diversity of mankind and Gunas belong to none for its verily exists in Nature.
