Whenever there is a Decline in Righteousness the Lord Himself will come

"Whenever and wherever ther is a decline in religious practice, O descendent of Bharata, and a predominant rise of irreligion-at that time I descend Myself."

"To deliver the pious and to annihilate the miscreants, as well as to re-establish the principles of religion. I myself appear, millennium after millennium". ~ (B.G. As It Is 4.8 & 9)
