“Mrusha” is a Sanskrit word that means “false” or “untrue.” In Jainism, “Mrusha Vachana” refers to false speech or lying, which is one of the types of wrong conduct related to the vow of Satya (truthfulness).

Bino sabd (simple words): Mrusha = झूठ (Jhooth), असत्य (Asatya), गलत (Galat).

In Jainism, speaking Mrusha (false speech) is strictly discouraged, as it leads to harm, attachment, and accumulation of karma. One should always practice truthfulness (Satya) in thought, word, and deed.
