vedas dont even has a name called hindu.there are only sampradayas.afaik the term arya is a changed/modified word.it is arsha(or something likethat) sampradayaIn which Veda is eating beef prohibited? Just show me that. How come Chandogya Upanishad clearly states that all animals and all plants are provided for our consumption by Lord Vishnu, without exception? Sure, protecting animals is mentioned, but it has been quoted out of context by the militant-vegetarian-brigade, which is hell bent on subverting the religion. Even the Indian Constitution guarantees Right to Life. Does that mean there is no death penalty?
Over a period of time, the invading or migrating Aryans, gradually gave up their nomadic lifestyle, and adopted a more agrarian and sedentary lifestyle. Due to this, the importance of animal husbandry gained importance, and new customs came into being. This is how cattle became as important as real estate today is. However, the metamorphosis that Indian society underwent, does not mean, at the beginning of Bronze Age, the customs and prohibitions were the same as those that came into existence in the later Iron Age. Hindutwavadis don't even acknowledge that Aryans came into India, where overwhelming evidence exists as to their original source being eastern Iran and western Afghanistan.
Regional customs are regional customs. Practice what you want, but please don't do it in the name of Vedas.
One is subset of the other. Show me a prohibition on eating beef, not from the Puranas and Smritis, but the Vedas.
though i believe the aryan nomads coming into india and conquering the lands,i have no substantial evidence to prove this.but one can find the quotes from great fighter bhishmacharya about origins of kuru empire in mahabharata.its somewhere above today's afghanistan and china.
even researchers believe that meru parvat is in this region by the quotes given by bhishmacharya.
wife of dhritarashtra ,gandhari is from afghanistan(gandharadesham)and sakuni is maternal uncle of kauravas
a person who has the knowledge of bramha (supreme) is a brahmin irrespective of birth.recieving holy thread is just to send you for education.even kshatriyas,vysyas wear it.once it is worn by all classes of people including women,but gradually given up.Being a Brahmin means being conversant with the Vedas, at least one of them. This is the fundamental of receiving a holy thread. Hence my questions. Otherwise, why claim to be a Brahmin? Just because of heredity? What religion is that? Surely not Hinduism. Also, your mention of caste is irrelevant. Caste has nothing to do with Hinduism, or being a Brahmin.
you can still see in some socially deprived classes wearing holy thread.
