Slokam 2

Karthaveeryarjuna takes on the responsibility of keeping the Kshatriya’s from taking ascendancy and assuming universal control of every other community.  Karthaveeryarjuna is himself  a kshatriya. The task of keeping the Kashatriyas in balance with other communities was proving to be too much for Karthaverryarjuna.  The Paramathma then takes on the avatar of Parasurama by being born on earth as the son of Jamadagni and Renukadevi.  He is born in the lineage of Bhrigu.

Extract from Wikipedia

Once, Lord Vishnu was reciting the Vedas to Lakshmi. After a long time, Lakshmi got bored. Angry, Lord Vishnu cursed her that she would be born on earth that very moment. She disappeared. Realizing his mistake, Lord Vishnu incarnates as Dhanaka, the son of King Kanaka of the Haihaya Dynasty. He married Lakshmi and their son was Krtavirya, the father of Kartavirya Arjuna. Later, Lord Dattatreya, blessed Kartavirya Arjuna with a thousand hands. But this made the king arrogant.

Kartavirya Arjuna (Sanskrit: कार्तवीर्य अर्जुन, Kārtavīrya Arjuna; also known as Sahasrabahu Arjuna or Sahasrarjuna) was a legendary king of an ancient Haihayas kingdom with capital at Mahishmati which is on the banks of Narmada River in the current state of Madhya Pradesh. Kartavirya was son of Kritavirya, king of the Haihayas. According to the Puranas, Haihaya was the grandson of Sahasrajit, son of Yadu. This is his patronymic, by which he is best known; he is also referred to simply as Arjuna. He is described as having a thousand hands and a great devotee of god Dattatreya. One of the several such accounts states that Arjuna conquered Mahishmati city from Karkotaka Naga, a Naga chief and made it his fortress-capital.^[1]

The Puranas recount that Kartavirya Arjuna and his army visited a rishi named Jamadagni, who fed his guest and the whole army with offerings from his divine cow Kamadhenu. The king demanded the cow for the betterment of his subjects; Jamadagni refused because he needed the cow for his religious ceremonies. King Arjuna sent his soldiers to take the cow. As the conflict developed among the Jamadagni and the King, Arjuna lost his temper and chopped off the head of Jamadagni. When Parashurama (Jamadagni's son and one of the Daśāvatāras of Vishnu) returned to the hermitage, he was informed of the context by his mother. In revenge, Parashurama killed the entire clan of Arjuna and the King with a battleaxe given to him by Shiva, eventually killing all kshatriyas, thus conquering the entire earth, which was then ruled by Brahmans. He enacted this wholesale eradication of the kshatriyas for 21 generations.^[6]

In another place a different character is given to him, and more in accordance with his behavior at Jamadagni's hut. "He oppressed both men and gods," so that the latter appealed to Vishnu for succor, who then came down to the earth as Parashurama for the special purpose of killing him.^[7]

May we abide by the code of conduct of the Paramathma,  in His effort to maintain lasting peace and progress of all His creations.
