नटाङ्गणन्यायः

It takes its origin from the conversation between a hero and a heroine on a theatrical stage in course of which the hero asks the heroine whose wife she is, and she says in reply that she is his wife, and is used to denote that the theatrical relation is false, its usefulness being only to produce a temporary and musing effect. Man’s life is also a stage of theatre, and its connection with others in various kinds of relationship is therefore nothing but an illusion.
