There is an interesting story in the epic Mahabharata that brings home this point. Towards the end of the Kurukshetra war, Ashwathama, being a loyal friend of slain king Duryodhan, wipes out the five children of Draupadi and also shoots the deadly brahmastra on the womb of deceased warrior Abhimanyu’s wife, Uttara, in order to eliminate the last seed of the Pandavas. Uttara beseeches Lord Krishna to protect her baby and the Lord obliges by keeping vigil inside her womb.
