Once Urvashi and Pururava were walking along the bank of a stream in animated conversation. Pururavas noticed a maiden knee deep in water washing clothes and for a second his concentration faltered. Urvashi went into a fit of jealous rage and ran away. So maddened was she that she stepped into Kartikeya's grove. Kartikeya is the God of War and women were forbidden to enter his grove and if they did so they would be turned into a creeper. This was the fate Urvashi met.
For many months Pururava searched for Urvashi. He prayed to the Gods for their favour. He recounted the numerous times he had fought shoulder to shoulder with them in their incessant war against the Demons. Kartikeya relented and gave Pururavas a crimson jewel and asked him to rub a particular creeper in his grove with it. When the king did so Urvashi was freed.
