In The Mrichchhakatika, the hero is a dignified righteous Brahman, a merchant of eminence, who has impoverished himself not by any slackness in his character or any attachment to vices, but by his superior and charitable temperament. He is blameless by nature and never spares in his acts of benevolence and munificence to other people in anguish or suffering.
Consequently, he spends away his assets and reduces himself almost to poverty.
He is married and has a son called Rohasena, by his wife Dhuta. But he is so inopportune that he fails to have fulfilled his little son's desire to have a little gold cart like his other rich friends rather than his own little clay cart given by his nurse.
Charudatta is, however, loved by a lady of rare beauty, Vasantasena, a quite well off courtesan.
After her meeting with Charudatta in a temple of Kamadeva, she becomes extremely amorous of Charudatta. He, too, feels love for her and they meet and spend a night together in the latter's house. But the course of their love doesn't run silky as a criminal Sansthanaka, a brother-in-law of the tyrannous king Palaka intervenes in their love and tries to seduce Vasantasena.
The dignified lady, however, refuses impudently and straight. Thereafter, the clownish criminal, becoming vengeful and nurtures a grudge against both the lovers. Sansthanaka, in due course, suddenly gets a chance to slay Vasantasena and arranges situations to purport Charudatta as her murderer.
Due to a benign error, Vasantasena gets into the cart of the villain, thinking it to be Charudatta's whom she is to meet at a flower-garden, outside the town.
Charudatta unproductively waits for Vasantasena and when her cart comes. A rebel, Aryaka, is found therein. Out of his good nature, Charudatta allows that rebel to use his cart and he leaves the place.
As Vasantasena arrives, Sansthanaka gets hold of her and eventually strangulates her. She becomes cataleptic and drops down on the ground. Taking her as deceased, he leaves her body in a bush. Vasantasena, however, remains alive and is nursed and brought back to her full strength by a Buddhist monk in a close by monastery.
In the interim, Charudatta is accused of killing Vasantasena for her riches. Enough evidence, as available, is put by Sansthanaka for his punishment. The king passes a death sentence against Charudatta. But before the execution of Charudatta, Vasantasena appears alive along with the Buddhist monk. The entire situation now totally changes. Charudatta is released while Sansthanaka is arrested.
There is also a political change in the city and King Pal aka was dismissed and killed by the rebels. Aryaka, their leader, becomes the new king. He restores Charudatta to his former position of fortune and eminence, and also pardons the villain Sansthanaka who had already been arrested.
Thereafter, there is the union of the solemn lovers-Charudatta and Vasantasena. Charudatta's first wife has no avowal to have another wife for her husband. Vasantasena is permitted to relinquish her position as a courtesan and embrace the life of a legally sanctioned wife.
Thus, the play shows the happy amalgamation of love and the eventual success of virtue over vice. The triumph of true love and profound virtue make the entire theme of the play, showing that vice and iniquitous demeanour do not finally pay.
The Mrichchhakatika, supposed to be written by Sudraka, is for the most part regarded as the symbol of Prakarana plays. This is, in effect a play not based on some ancient classical story or the performances of classical heroes or gods and goddesses. The Mrichchhakatika, as a Prakarana play, is concerned with general life led in a society and the characters involved are fairly familiar and pragmatic in the milieu of the age the play belongs to.
