invocation

Invocation is the act of calling upon a deity, spirit, or supernatural force, typically through prayer, ritual, or spoken formula, to seek guidance, assistance, or presence. It is a practice found in numerous religious, spiritual, and esoteric traditions, where it serves to establish a connection between the human and the divine or metaphysical realms. Invocation can be directed toward a singular deity, multiple deities, spirits, or abstract forces, and may involve formal liturgies, spontaneous prayers, chants, or symbolic actions. Unlike evocation, which is generally understood as calling a spirit to appear outside the practitioner, invocation often implies inviting the entity to be present within or to closely align with the practitioner.
