Yama (Sanskrit: यम) or Yamarāja (यमराज) is the god of death, belonging to an early stratum of Vedic mythology. In Sanskrit, his name can be interpreted to mean "twin". In the Zend-Avesta he is called "Yima". According to the Vishnu Purana, his parents are the sungod Surya and Sanjna, the daughter of Visvakarman, sometimes called "Usha". He is the brother of the current Manu Vaivasvatha and of his older sister Yami, which H. H. Wilson indicates to mean the Yamuna river.
