The Bornless Ritual, also known as the Preliminary Invocation of the Goetia, or the Invocation of the Heart Girt with a Serpent, is often considered the proper preliminary invocation to the Ars Goetia since it was introduced as such by Aleister Crowley. Originally, grimoire magick did not include this particular ritual but routinely advised the magician (or "exorcist") to have a close bond to the heavenly powers before he meddle with demons (e.g. the Book of Abramelin, the Keys of Solomon, etc.). As Stephen Skinner says, "The Bornless One" is nowhere mentioned, for instance, in his recent translation of the Goetia of Dr. Rudd, as the ritual is of Greaco/Egyptian origin. Skinner argues that the ritual is in fact an exorcism. 
"I summon you Headless One, who created earth and heaven, who created night and day [...] I am the Favor of the Aion; my name is a heart encircled by a serpent" 
Crowley's text is:
"Thee I invoke, the Bornless one.
Thee, that didst create the Earth and the Heavens:
Thee, that didst create the Night and the day.
Thee, that didst create the darkness and the Light.
Thou art Osorronophris: Whom no man hath seen at any time.
Thou art Iabos:
Thou art Iapos:
Thou hast distinguished between the just and the Unjust.
Thou didst make the female and the Male.
Thou didst produce the Seed and the Fruit.
Thou didst form Men to love one another, and to hate one another.
I am Ank F N Khonsu Thy Prophet, unto Whom Thou didst commit Thy Mysteries, the Ceremonies of Khem:
Thou didst produce the moist and the dry, and that which nourisheth all created Life.
Hear Thou Me, for I am the Angel of Apophrasz Osorronophris: this is Thy True Name, handed down to the Prophets of Khem.
Hear Me: Ar: Thiao: Reibet: Atheleberseth: A: Blatha: Abeu: Eben: Phi: Chitasoe: Ib: Thiao.
Hear Me, and make all Spirits subject unto Me: so that every Spirit of the Firmament and of the Ether: upon the Earth and under the Earth: on dry Land and in the Water: of Whirling Air, and of rushing Fire: and every Spell and Scourge of God may be obedient unto Me.
I invoke Thee, the Terrible and Invisible God: Who dwellest in the Void Place of the Spirit: Arogogorobrao: Sochou: Modorio: Phalarchao: Ooo: Ape, The Bornless One: Hear Me!
Hear Me: Roubriao: Mariodam: Balbnabaoth: Assalonai: Aphniao: I: Tholeth: Abrasax: Qeoou: Ischur, Mighty and Bornless One! Hear Me!
I invoke Thee: Ma: Barraio: Ioel: Kotha: Athorebalo: Abraoth: Hear Me!
Hear me! Aoth: Aboth: Basum: Isak: Sabaoth: Iao:
This is the Lord of the Gods:
This is the Lord of the Universe:
This is He Whom the Winds fear.
This is He, Who having made Voice by His Commandment, is Lord of All Things; King, Ruler, and Helper. Hear Me!
Hear Me: Ieou: Pur: Iou: Pur: Iaot: Iaeo: Ioou: Abrasax: Sabriam: Oo: Uu: Ede: Edu: Angelos tou theou: Lai: Gaia: Apa: Diachanna: Chorun.
I am He! the Bornless Spirit! having sight in the Feet: Strong, and the Immortal Fire!
I am He! the Truth!
I am He! Who hate that evil should be wrought in the World!
I am He, that lightningeth and thundereth.
I am He, from whom is the Shower of the Life of Earth:
I am He, whose mouth flameth:
I am He, the Begetter and Manifester unto the Light:
I am He, the Grace of the World:
"The Heart Girt with a Serpent" is My Name!
Come Thou forth, and follow Me: and make all Spirits subject unto Me so that every Spirit of the Firmament, and of the Ether: upon the Earth and under the Earth: on dry land, or in the Water: of whirling Air or of rushing Fire: and every Spell and Scourge of God, may be obedient unto me! Iao: Sabao: Such are the Words!"
