“He must be killed at once!” exclaimed Mareecha. “Not a soul on this earth can kill my mother and get away with it.” These were Mareecha’s feelings following Thataka’s death at the hand of Rama in the forest of Sidhasrama. Just before Mareecha was set to pounce, Rama pivoted and released an arrow, catapulting Mareecha into the sea of Madartha with the force of the strike. Unconscious, Mareecha was guided by the current onto the sandy cove. At the break of dawn the next day, Mareecha awoke to the screech of feral baboons. Startled, he jolted up and looked around – there was nothing but water his east and jungle in remaining directions. “I can’t survive in there,” he remarked, “I’ll be eaten by some voracious beast before sundown.” He panicked and called upon the one being that could help him out of his situation – Yatha, overseer of the jungle. “Yatha,” he pleaded, “return me to my village and I promise to live a life of rectitude.” “No.” Replied Yatha. “You must live in the jungle AND carry out good works for those in need.” Mareecha, frayed by the approaching sounds of the jungle creatures, agreed. Abiding by the commands of Yatha, Mareecha lived on the outskirts of the jungle practicing goodwill and spirituality.

Meanwhile, Ravana, insatiable because of the description of Sita, burst into Mareecha’s living accommodation. “Mareecha! My uncle, I am in dire need of your help.” said Ravana. “I know that under your agreement with Yatha you can assist only those in need. And, well, I’m in need.” Ravana pleaded, “The love of my life is being held captive by two mortals. Won’t you aid me in liberating her?” Mareecha, fulfilling his oath to Yatha, obliged. “Present yourself as a fox of the forest and draw her away from her captors and towards me” said Ravana. Mareecha lauded the idea for its feasibility, “What a fantastic idea!”
Upon arrival near the camp, Mareecha noticed just who her captors were – Rama and his brother. “I can’t; I can’t do this,” he quipped. Just the look of Rama’s face made Mareecha frightened. “He’ll surely take my life if he catches me and realizes who I really am,” said Mareecha. So he darted for the thick of the forest and Rama chased shortly behind. “I just wanted a life of tranquility,” thought Mareecha as he pondered in what would surely be his last moments. Rama, realizing that this was no ordinary fox, drew a spear and hurled it in the path of Mareecha. It grazed Mareecha in the tail but not such it would do him any harm. “Yatha, please help me out of this!” claimed Mareecha. “I thought this was an innocuous instance of help. Rama tricked me!” Yatha, understanding the nature of what unfolded, granted Mareecha his wish and whisked him back to his hut. “Surely now you know who and who not to help, right?” said Yatha. “Your nephew wanted nothing more than to use you in order to fulfill his lustful desires.” Ravana made away with Sita and arrived back home with a new woman in hand. Because of the wrong he did to a harmless Rama, Mareecha felt compelled to reach out to Rama and offer his services in recapturing Sita.

Authors note: I chose to write this story in a third person style in order to provide more depth to the character Mareecha. It seemed as if he was forced to comply in the actual story and I wanted to provide more details as well as his cognitions moving forward. In my story I altered the animal that is pursued as well as Ravana's character -- I made him more of a deceiver in this retelling.
