Hear Vedic literature, not rubbish transmitted by man-made machines

[Bhakti Vikasa Swami]

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.
