Your devotion to God has to be continuous, uninterrupted, like the flow of oil from one vessel to another. You may have observed that the young monkey relies on its own strength to protect itself.  Wherever its mother might jump, it has to attach itself fast to the mother's belly and should not release its hold, even if pulled apart. So too, as a devotee you must stand the test at the hands of the Lord and hold on to the Lord's Name at all times and under all conditions, tirelessly, without the slightest trace of dislike or disgust, bearing ridicule and criticism of the world and overcoming the feelings of shame and defeat. Practice of devotion of this kind is called Markatakishora Marga. Prahlada, a great child devotee of the Lord, practiced this kind of devotion.
