Krishna on Karma~A short story

When Lord Krishna returned home after the battle of Mahabharata,Rukmani confronted him“How could you be party to the killing of Guru Drona and Bheeshma, who were such righteous humans and had a lifetime of righteousness behind them.”Initially Lord Krishna avoided her questions but when she did not relent, he replied “No doubt they had a lifetime of rightousness behind them but they both had committed one single sin that destroyed all their lifetime of righteousness”
Rukmani asked “And pray tell,what was that sin?”Lord Krishna replied“They were both present in the court when a lady (Draupadi) was being disrobed and being elders they had the authority to stop it but they did not.This single crime is enough to destroy all righteousness of this world”Rukmani asked “But what about Karna,what was his fault?He was known for his charity.No one went emptyhanded from his doorstep. Why did you have him killed?” 

Lord Krishna said “No doubt Karna was known for his charity.He never said ‘No’ to anyone who asked him for anything.But when Abhimanyu fell after successfully fighting an army of the greatest warriors and lay dying, he asked for water from Karna who stood nearby.There was a puddle of clean water where Karna stood but not wanting to annoy his friend Duryodhan, Karna did not give water to a dying man.In doing so his charity of a lifetime was destroyed.Later in battle,it was the same puddle of water in which the wheel of his chariot got stuck and he was killed.” Understand that your one act of injustice can destroy your whole life of honesty. This story is great example of Karma Theory in relation to a Path towards Prosperity. So,with Awareness,only create your life's Karma account with complete honest righteousness.
