future, it may be possible to retrieve all spoken words. Scientists theorize that radio waves which have been transmitted into the universe could possibly reverberate forever. This idea may provide a useful analogy for understanding the nature of spoken words as sound current. If, as modern science contends, sound waves are indestructible, perhaps it is also possible that the words which Lord Krishna spoke to Arjuna during the war chronicled in the Mahabharata still exist and it might even be possible to retrieve those words. The pundits of the Vedas claim that the sounds of the Vedas are always reverberating, are eternal, and therefore, not of human origin. Vedic scholars use this idea about the indestructibility of sound waves to support the idea that shabad" (sound) is indestructible.
It is, therefore, believed that the ancient rishis perceived the manifestations of the spiritual, eternal, and divine knowledgel2 through the divine intelligence they attained in the state of samadhi (state of union with the Divine). Later these mystical insights were rendered into the written text.
Sage Yaskacharya records in a hymn:
The seers saw the mantras and therefore, they are known as rishis. (Nirukta, 2/3/11)
