Èṣù is a pivotal Òrìṣà/Irúnmọlẹ̀ in the Yoruba spirituality known as ìṣẹ̀ṣe. Èṣù is a prominent primordial Divinity who descended from Ìkọ̀lé Ọ̀run, and the Chief Enforcer of natural and divine laws - he is the Deity in charge of law enforcement and orderliness. As the religion has spread around the world, the name of this Orisha has varied in different locations, but the beliefs remain similar.

Orishas - correct spelling: singular - òrìṣà, plural - òrìṣàs - are divine spirits that play a key role in the Yoruba religion of West Africa and several religions of the African diaspora that derive from it, such as Haitian Vaudou, Cuban, Dominican and Puerto Rican Santería and Brazilian Candomblé. The preferred spelling varies depending on the language in question: òrìṣà is the spelling in the Yoruba language, orixá in Portuguese, and orisha, oricha, orichá or orixá in Spanish-speaking countries.
