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 kṣetra-ja 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 Phālguna (February-March), and therefore he is also called Phālguni. 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 Ādityas (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 Śataśṛṅga. He married four wives—Draupadī, Subhadrā, Citrāṅgadā and Ulūpī—from whom he got four sons of the names Śrutakīrti, Abhimanyu, Babhruvāhana and Irāvān respectively.
During his student life he was entrusted to study under the great professor Droṇācārya, along with other Pāṇḍavas and the Kurus. But he excelled everyone by his studious intensity, and Droṇācārya was especially attracted by his disciplinary affection. Droṇācārya accepted him as a first-grade scholar and loved heartily to bestow upon him all the blessings of military science. He was so ardent a student that he used to practice bowmanship even at night, and for all these reasons Professor Droṇācārya was determined to make him the topmost bowman of the world. He passed very brilliantly the examination in piercing the target, and Droṇācārya was very pleased. Royal families at Maṇipur and Tripura are descendants of Arjuna's son Babhruvāhana. Arjuna saved Droṇācārya from the attack of a crocodile, and the Ācārya, being pleased with him, rewarded him with a weapon of the name brahmaśira. Mahārāja Drupada was inimical toward Droṇācārya, and thus when he attacked the Ācārya, Arjuna got him arrested and brought him before Droṇācārya. He besieged a city of the name Ahichhatra, belonging to Mahārāja Drupada, and after taking it over he gave it to Droṇācārya. The confidential treatment of the weapon brahmaśira was explained to Arjuna, and Droṇācārya was promised by Arjuna that he would use the weapon if necessary when he (Droṇācārya) personally became an enemy of Arjuna. By this, the Ācārya forecasted the future battle of Kurukṣetra, in which Droṇācārya was on the opposite side. Mahārāja Drupada, although defeated by Arjuna on behalf of his professor Droṇācārya, decided to hand over his daughter Draupadī to his young combatant, but he was disappointed when he heard the false news of Arjuna's death in the fire of a shellac house intrigued by Duryodhana. He therefore arranged for Draupadī's personal selection of a groom who could pierce the eye of a fish hanging on the ceiling. This trick was especially made because only Arjuna could do it, and he was successful in his desire to hand over his equally worthy daughter to Arjuna. Arjuna's brothers were at that time living incognito under agreement with Duryodhana, and Arjuna and his brothers attended the meeting of Draupadī's selection in the dress of brāhmaṇas. When all the kṣatriya kings assembled saw that a poor brāhmaṇa had been garlanded by Draupadī for her lord, Śrī Kṛṣṇa disclosed his identity to Balarāma.
