Invocation of the Agathodaimon
"The invocation was originally used as an exorcism and invoked the “Headless One.” The Golden Dawn and Aleister Crowley versions changed this to the “Bornless One”… the invocation calls upon the most ultimate and infinite divinity beyond all conception of space and time. The individual is then identified as inseparable from that divinity, awakening the logos or divine spark within. The original can be found in PGM V 96-172. The Crowley version can be found in his Liber Samekh…If you are pressed for time, but want to perform a similar invocation, I have also used the following invocation to great success. I have found it is most potent when performed in Greek, so I include it here in its original language."
