A discourse of Swami Vivekananda on Mahabharatam :
Delivered at the Shakespeare Club, Pasadena, California, February 1, 1900
Now, you know, in every society there are stages of development. Behind this epic there is a wonderful glimpse of the ancient historic times. The author of the poem mentions the fact of the five brothers marrying the same woman, but he tries to gloss it over, to find an excuse and a cause for such an act: it was the mother's command, the mother sanctioned this strange betrothal, and so on. You know, in every nation there has been a certain stage in society that allowed polyandry — all the brothers of a family would marry one wife in common. Now, this was evidently a glimpse of the past polyandrous stage.
In the meantime, the brother of the princess was perplexed in his mind and thought: "Who are these people? Who is this man whom my sister is going to marry? They have not any chariots, horses, or anything. Why, they go on foot!" So he had followed them at a distance, and at night overheard their conversation and became fully convinced that they were really Kshatriyas. Then King Drupada came to know who they were and was greatly delighted.
Though at first much objection was raised, it was declared by Vyâsa that such a marriage was allowable for these princes, and it was permitted. So the king Drupada had to yield to this polyandrous marriage, and the princess was married to the five sons of Pandu.
Then the Pandavas lived in peace and prosperity and became more powerful every day. Though Duryodhana and his party conceived of fresh plots to destroy them, King Dhritarashtra was prevailed upon by the wise counsels of the elders to make peace with the Pandavas; and so he invited them home amidst the rejoicings of the people and gave them half of the kingdom. Then, the five brothers built for themselves a beautiful city, called Indraprastha, and extended their dominions, laying all the people under tribute to them. Then the eldest, Yudhishthira, in order to declare himself emperor over all the kings of ancient India, decided to perform a Râjasuya Yajna or Imperial Sacrifice, in which the conquered kings would have to come with tribute and swear allegiance, and help the performance of the sacrifice by personal services. Shri Krishna, who had become their friend and a relative, came to them and approved of the idea. But there alas one obstacle to its performance. A king, Jarâsandha by name, who intended to offer a sacrifice of a hundred kings, had eighty-six of them kept as captives with him. Shri Krishna counselled an attack on Jarasandha. So he, Bhima, and Arjuna challenged the king, who accepted the challenge and was finally conquered by Bhima after fourteen days, continuous wrestling. The captive kings were then set free.
Then the four younger brothers went out with armies on a conquering expedition, each in a different direction, and brought all the kings under subjection to Yudhishthira. Returning, they laid all the vast wealth they secured at the feet of the eldest brother to meet the expenses of the great sacrifice.
