Sir, I read your response regarding the caste system in Indian society. But can you kindly enlighten me, the pros and cons of Intercaste marriage? Does a Brahmin marrying a lower caste person looses her 'Brahmanatva'? I heard from elders, and also read in books that if we perform good karma, we take birth in brahman caste. Marrying lower caste person does it detoriates karma? I am confused. Kindly eloborate
