While continuing from the previous verse to glorify the sense of hearing dedicated to the Lord, King Parikshit mentions the other senses also, so that we gain a complete picture of Krishna consciousness. Here he declares that without any connection to Krishna, the Supreme Lord, all the organs of the body become useless. A similar statement is made by Saunaka Rishi in the Second Canto, Third Chapter, verses 20 to 24.
Srila Visvanatha Cakravarti mentions that the senses should work together in Krishna consciousness. In other words, whatever the eyes or the ears experience, the mind should simply remember Krishna, who is within all things.
