Dhritraashtra's Sons and Others

Janamejaya said - "Tell me the names of Dhritraashtra's sons beginning with the eldest one." Vaishampaayan Jee said - "They were - Duryodhan, and Yuyutsu, and also Duhsasana; Dusaha and Duhshal, and then Durmukha; Vivinsati, Vikarna, Jalasandha, Sulochan, Vind and Anuvind, Durdharsh, Subaahu, Dush-pradarshan; Durmarshan, Dushkarn, Karn; Chitra and Vipachitra, Chitraaksh, Chaaruchitra, and Angad, Durmad, Dush-pradarsh, Vivitsu, Vikat, Sama; Urananabh, Padmanaabh, Nand Upanandak; Sanapati, Sushen, Kundodar, Mahodar; Chitrabaahu, Chitravarmaa, Suvarmaa, Durvirochan; Ayovahu, Mahaabaahu, Chitrachapa and Sukundala, Bheemveg, Bheembal, Valaaki, Bheemvikram, Ugraayudh, Bheemaearaa, Kanakaayu, Dridhaayudh, Dridhavarmaa, Dridhakshatra, Somkeerti, Anaadar; Jaraasandh, Dridhasandh, Satyasandh, Sahastraveh; Ugrashravaa, Ugrasen, Kshemamoorti; Aparaajit, Pandit, Vishaalaksh, Durdhar, Dridhahasta, Suhast, Vaatveg, Suvarch; Aadityaketu, Vahavaas, Naagdatt Anuyain; Nishaangee, Kuvachee, Dandee, Dandadhar, Dhanugraha; Ugra, Bheemrath, Veer, Veerabaahu, Alolup; Abhaya, Raudrakarmaa, Dridharath; Anadrishya, Kundved, Viravi, Dheerghlochan; Deerghbaahu; Mahaabaahu; Vyudhoru, Kanakaangan; Kundaj and Chitrak.

Note - These names do not match with the names of Dhritraashtra's sons mentioned in the war time when they were killed by Bheem. See the list. Besides Gaanguli's Sanskrit version (Book 1, Chp 61) doesn't give these names at the place where he has provided them in his English translation version - Book I, Section LXVII (Book 1, Section 67).

Dhritraashtra also had a daughter named Dushala who was over and above these hundred sons. And Yuyutsu who was Dhritarashtra's son by a Vaishya wife, was also over and above the hundred. Thus, O king, I have recited the names of the hundred sons and also that of the daughter (of Dhritarashtra). You now known their names according to the order of their births. Dushalaa was married to Jayadrath, the King of Sindhu, according to the advice of Shakuni.

Yudhishthir was a portion of Dharm Raaj. Bheemsen was was the portion of Vaayu Dev. Arjun was a portion of Indra and Nakul and Sahadev were the portions of Ashwinee Kumaar. Varch, who was the son of Som, was born as Abhimanyu. Before incarnating, Som said to the celestials, "I cannot part my son, he is very dear to me, so his life should be short on Prithvi. It is celestials duty to kill Asur, so let him go there but not for too long time. Nar will be born as Indra's son, and will be known as Arjun, the son of Paandu, so let him be his son and should stay only for 16 years. When he will be of 16 years, a war will take place, and a day will be there when Nar and Naaraayan will not be there to fight. A Chakra Vyooh will be designed by enemies, so let him defeat all his enemies at that time. He will kill one fourth army of enemy in half a day time. As the day will be over, my son should reappear before me." Hearing this all celestials worshipped him. This was  the account of birth of your grandfather. Dhrishtdyumn was a portion of Agni Dev. Shikhandee was first a female and an incarnation of a Raakshas. The five sons of Draupadee were the Vishwaas Devtaa.

Shoorsen was the father of Vasudev. He had a daughter named Prithaa. He promised the son of his paternal aunt (Buaa) Kuntibhoj, who had no child, to give his first-born child in the expectation to gain some favors. So as his first child was born, he gave her to him. There she used to receive Braahman and guests. One day she attended Rishi Durvaasaa. Durvaasaa got very pleased with her services, so he said to her - "I am very pleased with you. Take this Mantra, you can invoke any Devtaa by this Mantra and you might have children from him. After a while, just curiosity sake she invoked Soorya Dev and Soorya Dev gave her a son who came with a Kavach (armor, or protection cover) and earring on his body. Kuntee with the fear of being maiden, flowed him in water. The child was taken up by the husband of Raadhaa, and both adopted him as their son and named him Vasusen.

When he grew up, he became excellent in weapons and there was nothing he did not give to Braahman. To protect his own son, Indra assumed the guise of a Braahman and begged his Kavach and earrings. Surprised at his donation, Indra gave him a Power and said - "To whoever you will aim this power, he will be slain." His original name was Vasusen, but because of his deeds he came to be known as Karn. Later he became the counselor and friend of Duryodhan. And whose name was Vaasudev was Naaraayan himself; and Baladev (Balaraam) was a portion of Shesh Naag. Pradumn was Sanat Kumaar. Thus celestials incarnated on Prithvi.

Apsaraa also incarnated on Prithvi. 16,000 portions of them came on Earth as Vaasudev's wives. A portion of Shree (Lakshmee) incarnated in the house of Bheeshmak as Rukminee. Draupadee was the portion of Shachee. Siddhi and Dhriti became the mothers of five - Kuntee and Maadree; and Mati became the daughter of Subal - Gaandhaaree.

Thus this is the account of incarnations.
