The Svapnavāsavadattam is undoubtedly the poet's masterpiece and the fruit of his mature genius. That it was considered the best among Bhasa's works in
RajaSekhara's time (9th century AD) is proved from the well-known verse of that poet: भासनअकचक्रेऽपि च्छैकेः क्षिप्तैः परीक्षितुम्। स्वप्नवासवदत्तस्य दाहकोऽभून्न पावकः।।1
As with many other plays, the plot of this one, too, has been drawn from the legends and stories of Udayan and Vasavdatta, which were prevalent at the time. Bhasa's Svapnavāsavadattam is in effect a sequel to his play Pratijiiayaugandharayanam. The main theme of the drama is the sorrow of Udayana for his wife Vasavadatta, believed by him to have perished in a fire.The legend has been taken from the Kathasaritsagar.
If Pratifflayaugandharayanam is a play of political intrigue closely intertwined with the thrilling adventures of romantic love making, Svapnavasavadattam is an immortal saga of dedicated love set in the hard frame-work of political intrigue.
Svapnavāsavadattam, in six acts, pictures the self-denying love of Vasavadatta for Udayana which impels her to make the most challenging sacrifice a woman may be called upon to make, of willingly
