Vidhushaka means a character that creates laughter by making fun. He is fond of eating, coward, quarreling, quarrelsome and jester-joker. He creates laughter by his utterance, behavior, dress and sometimes by his distorted gestures.
As a person he is Brahmin. A tuft crooked long stick in his hand and bizarre/grotesque dress are his marks. Audience recognize him before he speaks anything coming to the stage. He is a friend of the hero. Generally his role is quite silly. He does such things which give an impression of spoiling the heroes deeds. But ultimately the hero's deeds, actions improve. His presence in Sanskrit plays is inevitable.
In the present Mruchchakatika play the name of Vidhshak a jester is Maitreya. In the present lesson he behaves like a foolish man and generates good laughter.
