The Vedas are known as the earliest record of Indo Aryan civilization. These are the most sacred books of India. They are containing spiritual knowledge of all aspects of life. The Vedas form the highest religious authority for all aspects of Hinduism and are a respected source of knowledge for human generally. The word Veda means wisdom or knowledge; these are the words of god through human speech. Now a days all Hindu customs, traditions are regulated by the principles of Vedas. All the Hindu functions like birth, death, marriage etc. are guided by Vedic rituals.
It is very difficult to find the actual origin of the Vedas, as the ancient Hindus have not kept any historical record of their religious and political realization. So it is very difficult to determine original period of Vedas. It is thought, it may be 1700 BCE, the late Bronze Age. Tradition suggests that humans were revealed by the sages, who were known as the “mantra drashta” of human. The formal documentation of vedas is done by Vyasa Krishna Dwaipayana around 1500 BC.
