ParitraaNaaya SaadhoonaaM

परित्राणाय साधूनाम्
(To protect the virtuous)

In the Geetaa, the Lord promises: "When Dharma degenerates and Adharma prevails, I descend to earth in human garb to reestablish and uphold Dharma in every Yuga." Further, He comes to protect the virtuous and vanquish the wicked.

Jesus came and returned. Muhammad came and returned. Only our Lord comes again and again because like the cycle of birth and death, the waxing-waning cycle of life in the world is inevitable. In His discourse, He says He had delivered the message to the Sun but that it is weakened over the ages. Thus, God's reappearance is necessary time and again.

Good people think, "Is the time not wicked enough with Bush and Mush around for God to descend now?" But are they so virtuous that God should descend? Judge yourself first before sitting on judgement on God's Wisdom and His actions, what He should do and when. Reform and improve yourself and God will take care of others. Otherwise when He comes He will vanquish you for your wickedness.
(I am reminded of a short speech by a passenger on the bus to Moolky. His neigbhour was so wicked, he said, that he would like an atom bomb be dropped on the neigbhour's house!)

When we see a movie, we want the villain to be punished fast. But punish the villain in yourself first.
