The common man is drawn by external pomp and apparent motives. So he judges the leelas (Divine sport) as common and even low. The inner meaning and purpose are not easily patent to all. But the Lord can never engage Himself in purposeless and paltry activities. His advent is for the uplift of the world from the morass of wickedness and unrighteousness, for fulfilling the needs of those devoted to Him, for the reestablishment of righteousness and morality, and for the revival of the Vedas. He has to take into account the merit acquired by each in previous lives and shower His grace accordingly. His leelas or Divine activities are so shaped that they suit the time, the person, the aspiration and the compassion which cause each shower of grace!
