today's brahmin caste, better follow the normally accepted code of conduct ie equality before law, before God and before their fellow humans. i think the brahmin caste had separate rules in the past milleniums, and even to smell those laws, let alone read it, may put us at hazard with current day values.
we live in 21st century, where information follows the speed of light and so do ideas.
we cannot live by religion or by reverting to old laws. this, our immediate ancestors for the past 100 years understood, and little by little have been watering down, what they felt was inane or arcane practices of life, widowhood, female emancipation and above all the concept of caste itself.
ofcourse, if you want to know, how far we have fallen, or still falling, any understanding of the old laws is good. all of us better know what the universal law today is, and not to accept it, is to bring grief upon oneself.
personally, i think, separate laws to the brahmin way of life, is best consigned to the dungheap of history, along with mein kampf and protocols of the elders of zion.
