After the conclusion of the war, the Pandavas take charge of Hastinapura, the undivided realm of their ancestors. Yudhishira appointed Arjuna as the Yuvaraj of Hastinapura. Yudhishthira decided to hold the Ashvamedha Yagna, or “horse sacrifice”, to grant them the title of Chakravarti (“Emperor”). Arjuna led the armed forces which followed the horse around its random wanderings. He received the submission of many kings, either without or following an armed confrontation. He was thus instrumental in the expansion of the Pandava domains. Arjuna built the Aranmula Parthasarathy Temple during his conquest in South India. Aranmula Parthasarathy Temple is one of the “Divya Desams”, the 108 temples of Vishnu revered by the 12 poet saints, or Alwars located near Aranmula, a village in Pathanamthitta District, Kerala, South India. The temple is dedicated to Parthasarathy, Lord Krishna’s role as Arjuna’s Charioteer in the Mahabharata war. Legend has it that Arjuna built this temple, to expiate for the sin of having killed Karna on the battlefield, against the dharma of killing an unarmed enemy.
