In history there are two Arjunas. One is Kārttavīrya Arjuna, the King of Haihaya, and the other is the grandfather of the child. Both the Arjunas are famous for their bowmanship, and the child Parīkṣit is foretold to be equal to both of them, particularly in fighting. A short description of the Pāṇḍava Arjuna is given below:
Pāṇḍava Arjuna: The great hero of the Bhagavad-gītā. He is the kṣatriya son of Mahārāja Pāṇḍu. Queen Kuntīdevī could call for any one of the demigods, and thus she called Indra, and Arjuna was born by him. Arjuna is therefore a plenary part of the heavenly King Indra. He was born in the month of Phalguna (February-March), and therefore he is also called Phalguni. When he appeared as the son of Kuntī, his future greatness was proclaimed by air messages, and all the important personalities from different parts of the universe, such as the demigods, the Gandharvas, the Adityas (from the sun globe), the Rudras, the Vasus, the Nāgas, the different ṛṣis (sages) of importance, and the Apsarās (the society girls of heaven), all attended the ceremony. The Apsarās pleased everyone by their heavenly dances and songs. Vasudeva, the father of Lord Kṛṣṇa and the maternal uncle of Arjuna, sent his priest representative Kaśyapa to purify Arjuna by all the prescribed saṁskāras, or reformatory processes. His saṁskāra of being given a name was performed in the presence of the ṛṣis, residents of Śatasṛṅga. He married four wives, Draupadī, Subhadrā, Citrāṅgadā and Ulūpī, from whom he got four sons of the names Śrutakīrti, Abhimanyu, Babhruvāhana and Irāvān respectively.
