The Amavasaya of Chaitra month is the last day of Hindu year and on the next day begins the new year according to Hindu calendar and the Chaitra Navratras. The ekadashi that falls after the navratras is called Kamada ekadashi or Chaitra shukla ekadashi. Chaitra Sudi Ekadashi grants all the wishes.
Once Yudhishthira Maharaja said, 'Oh Lord Krishna, Oh Vasudeva, please accept my humble obeisance's. Please describe to me the Ekadashi that occurs during the light part of the month of Chaitra . What is its name, and what are its glories?'
Lord Shri Krishna replied, 'Oh Yudhishthira, please listen to Me attentively as I relate the ancient history of this sacred Ekadashi, a history Vasishtha Muni once related to King Dilipa, the great-grandfather of Lord Ramachandra.'
King Dilipa asked the great sage Vasishtha, "Oh wise brahman, I wish to hear about the Ekadashi that comes during the light part of the month of Chaitra. Please describe it to me."
Vasishtha Muni replied, Oh king, your inquiry is glories. Gladly shall I tell you what you wish to know. The Ekadashi that occurs during the light fortnight of Chaitra is named Kamada Ekadashi. It consumes all sins. It is very purifying, and it bestows the highest merit upon one who faithfully observes it. Oh king, now hear an ancient history which is so meritorious that it removes all one's sins simply by being heard.
Once, long ago, there was a city named Ratnapura and King Pundarika was its ruler. It had mostly Gandharvas, Kinnaras, and Apsaras among its citizens.
Among the Gandharvas were Lalit and his wife Lalita, who was an lovely couple. These two were intensely attracted to each other. Lalita loved her husband dearly, and likewise he constantly thought of her within his heart. They were inseparable.
Once, in the court of King Pundarika, many Gandharvas were singing, Lalit was one among them. While singing Lalit could not help thinking about his beloved, and because of this distraction he lost track of the song's melody. Lalit sang the song improperly, and one of the envious snake named kakort who was in attendance at the king's court complained to the king that Lalit ws lost in the thought's of his wife that's because he lost track and sang improperly. The king became furious upon hearing this, and he shouted, 'Oh foolish knave, because you were lustfully thinking of a woman instead of reverently thinking of your king as you performed your court duties, I curse you to at once become a Demon !, a man-eating demon with a terrified apperance.
