When the human being gives up the process of hearing about the all-pervading Personality of Godhead, he becomes a victim of hearing rubbish transmitted by man-made machines. Machinery is not bad, because through the machine one can take advantage of hearing about the Lord, but because machinery is used for ulterior purposes, it is creating rapid degradation in the standard of human civilization. It is said here that it is incumbent upon the human beings to hear about the Lord, and scriptures like the Bhagavad-gita and Srimad-Bhagavatam are made for that purpose. Living beings other than human beings have no ability to hear such Vedic literatures. If human society gives itself to the process of hearing the Vedic literature, it will not become a victim to the impious sounds vibrated by impious men who degrade the standards of the total society.
