lokeśvara. (T. ’jig rten dbang phyug; C. shizizai; J. sejizai; K. sejajae 世自在). In Sanskrit, “lord of the world”; a polysemous term in a Buddhist context. Lokeśvara is one of the many titles of respect given to a buddha. The term also denotes several different divinities (Deva) who are worshipped or called upon for favor; many of these gods were assimilated from the ancient Indian pantheon. Thus, the term can refer to any number of deities that are invoked by Buddhist practitioners. Lokeśvara is also one of the common variant names of the Bodhisattva Avalokiteśvara. Finally, Lokeśvararāja is the name of one of the fifty-three buddhas of the past mentioned in the Sukhāvatīvyūhasūtra and the one who gave the prediction of future buddhahood to Dharmākara, the eventual buddha Amitābha.
