What does “our senses are meant for Krishna’s satisfaction” mean?

From Jagat Singh P
my friend once while reading the srila prabhupada’s book as it is ,quoted the statement about srila prabhupada ,which stated ” we are meant for the enjoyment of krishna ” he continued ,why prabhupada says that our senses are meant for satisfaction of krishna?. and he argued on that point.He was new to krishna consciousness ,and this kind of statement was never heard by him before , i understood that srila prabhupada there was trying to say something very intimate and devotional ,but i failed to properly explain him .could you please explain this matter in detail .what does it mean when we say that we are meant for satisfaction of krishna senses ,as prabhupada tells in purports
