PURPORT

As is stated in the Bhagavad-gita, one should try to know by advancement of knowledge about the Supreme Lord, the summum bonum of everything. Knowledge does not mean to know the laws of nature or of physical knowledge that are working by the direction of the Lord. The scientists are eager to hear about the physical laws that are working in the material nature. They are eager to hear through the medium of radio and television about the things which are taking place far away from them in other planets, but they should know that the power of hearing and the instruments for hearing were given to them by the Lord for hearing about the Self, or about the Lord. Unfortunately the power of hearing is misused in hearing the vibrations of mundane affairs. The great sages were interested to hear about the Lord through Vedic knowledge and nothing more. And that is the beginning of aural reception of knowledge.
