<span>The Vedas are inseparable from the Supreme Brahman. They embody the entire range of knowledge spanning the sacred and the secular. Their significance lies in the fact that the truths and thoughts they contain are eternal. Nobody invented or created them. The truths have always existed and the human race has received these in the manner of revelations. The Rishis of yore are known as Seers because they saw in their inner eye these profound thoughts that already existed. The method of transfer of knowledge is thus intuitive from the seers who interpreted the truths they discovered.</span>
