What is "heru-ra-ha"

Heru (literally " Horus sun-flesh", among other possible meanings) is a composite deity within Thelema, a religion that began in 1904 with Aleister Crowley and his Book of the Law. Heru-ra-ha is composed of Ra-Hoor-Khuit and Hoor-paar-kraat. He is associated with the other two major Thelemic deities found in The Book of the Law, Nuit and Hadit, who are also godforms related to ancient Egyptian mythology. Their images link Nuit and Hadit to the established Egyptian deities Nut and Hor-Bhdt ( Horus of Edfu).
