When the mind is singularly concentrated in meditation, all distractions are arrested. But until such interiorization is mastered, the devotee must persistently practice mind control; and he/she should also take common sense measures to eliminate, or at least minimize, invasive external stimuli. ~ Paramahansa Yogananda
We should choose a clean quiet place to meditate so that we are not disturbed. But more importantly, we should bring all our attention to a focal point, such as the breath. This persistent and intense concentration captivates the mind and over time will make it our willing helper, rather than the inner critic it can become without mindful control. The goal of effortless freedom is gradually earned by consistent, joyful discipline.
