Curse to Lord Vishnu

Once sage Narad was doing meditation for long period of time. He did that with such a strong will power that even Kamdeva could not able to disturb him. After that sage Narad was overwhelmed by feeling of pride. Lord Shiva listened to his arrogant statement. He advised Narad not to reveal this secret to anybody. But Narad was not satisfied. He wanted to give the news of his achievement to Lord Vishnu. So, he went to Lord Vishnu's abode and boasted about his feat of defeating Kamdeva. Vishnu decided to teach him a lesson by humbling his pride. Lord Vishnu uses his illusionary powers of “Maya”. While Narad was returning from Vaikuntha Loka, he saw a beautiful city. This city was ruled by a king named SheelNidhi. The king had a daughter and her Swayamvar was being organised. Narad, curiously entered the place were Swayamvar was being held. Narad was impress by the princess beauty. He returned back to Lord Vishnu and expressed his desire of marrying that princess. He also requested Lord Vishnu to make him as handsome as himself (Vishnu). The Lord Vishnu played a trick and gave the face of a monkey to Narad. The day of the Swayamvara came. Not knowing what had happened to his face, Narad reached the palace where the marriage ceremony was to take place. Princes stood before all the prospective match with garland in her hand. But she was taken aback when she saw Narad. She garlanded the handsome man standing beside Narad .The handsome man was none other than Lord Vishnu. Narad was astonished. He discovered his monkey-face in the reflection of a pool of water and became furious. He cursed Lord Vishnu that in one of his earthly re-incarnations would have to bear the pain of separation from his wife and only a monkey would be able to relieve him of his sufferings. Thus, when Vishnu was born as Rama, Hanuman helped him to free Sita from the bonds of Ravana.
