It would seem from a material point of view that to chant the same sixteen word Hare Krishna maha-mantra over and over and again for many hours a day, day after day, week after week, year after year, decade after decade would become unbearably boring. But actually that is not the fact. Why is this so?
The reality is that by chanting the Hare Krishna mantra with devotional love one is directly associating with Lord Sri Krishna, the Supreme Personality of Godhead, who has inconceivable innumerable attributes. Even if we were to connect with just one attribute of Krishna, we could go deeper and deeper into that one attribute with ever-increasing taste and bliss for all of eternity, what to speak of innumerable attributes!
Therefore there is absolutely no question of boredom in Krishna consciousness. Rather, it is material sense gratification which is indescribably, intolerably boring.
