The Holy Guardian Angel is representative of one’s truest divine nature. The term is equivalent with the Genius of the Golden Dawn, the Augoeides of Iamblichus, the Atman of Hinduism, and the Daemon of the gnostics.
In the system of Magick, the single most important goal is to consciously connect with one’s HGA, a process termed “Knowledge and Conversation.” By doing so, the magician becomes fully aware of his own True Will. For Aleister Crowley, this event was the single most important goal of any adept:
“It should never be forgotten for a single moment that the central and essential work of the Magician is the attainment of the Knowledge and Conversation of the Holy Guardian Angel. Once he has achieved this he must of course be left entirely in the hands of that Angel, who can be invariably and inevitably relied upon to lead him to the further great step—crossing of the Abyss and the attainment of the grade of Master of the Temple.”

Crowley became aware of the book entitled The Sacred Magic of Abramelin the Mage from George Cecil Jones, a member of the Golden Dawn. The book describes the full procedure for “Knowledge and Conversation” and gave him the term “Holy Guardian Angel.” Crowley sums up the book in The Equinox of the Gods:
“The aspirant must have a house secure from observation and interference. In this house there must be an oratory with a window to the East, and a door to the North opening upon a terrace, at the end of which must be a lodge. He must have a Robe, Crown, Wand, Altar, Incense, Anointing Oil, and a Silver Lamen. The terrace and lodge must be strewn with fine sand. He withdraws himself gradually from human intercourse to devote himself more and more to prayer for the space of four months. He must then occupy two months in almost continuous prayer, speaking as little as possible to anybody. At the end of this period he invokes a being described as the Holy Guardian Angel, who appears to him (or to a child employed by him), and who will write in dew upon the Lamen, which is placed upon the Altar. The Oratory is filled with Divine Perfume not of the aspirant’s kindling.
After a period of communion with the Angel, he summons the Four Great Princes of the Daemonic World, and forces them to swear obedience.
On the following day he calls forward and subdues the Eight Sub-Princes; and the day after that, the many Spirits serving these. These inferior Daemons, of whom four act as familiar spirits, then operate a collection of talismans for various purposes. Such is a brief account of the Operation described in the book.”
Crowley felt that attaining Knowledge and Conversation was so important, that he staked the claim that any other magical operation was, in a sense, evil. In Book 4 (Ch. 21) he explains:
“As was said at the opening of the second chapter, the Single Supreme Ritual is the attainment of the Knowledge and Conversation of the Holy Guardian Angel. It is the raising of the complete man in a vertical straight line…Any other operation is black magic…If the magician needs to perform any other operation than this, it is only lawful in so far as it is a necessary preliminary to That One Work.”
“There are, however many shades of grey. It is not every magician who is well armed with theory. Perhaps one such may invoke Jupiter, with the wish to heal others of their physical ills. This sort of thing is harmless, or almost so. It is not evil in itself. It arises from a defect of understanding. Until the Great Work has been performed, it is presumptuous for the magician to pretend to understand the universe, and dictate its policy.”
Crowley said that the Abramelin procedure was not the only way to achieve success in this endeavor:
“It is impossible to lay down precise rules by which a man may attain to the knowledge and conversation of His Holy Guardian Angel; for that is the particular secret of each one of us; as secret not to be told or even divined by any other, whatever his grade. It is the Holy of Holies, whereof each man is his own High Priest, and none knoweth the Name of his brother’s God, or the Rite that invokes Him.”
~ Book 4, One Star in Sight
The Adept will be free to concentrate his deepest self, that part of him which unconsciously orders his true Will, upon the realization of his Holy Guardian Angel. The absence of his bodily, mental and astral consciousness is indeed cardinal to success, for it is their usurpation of his attention which has made him deaf to his Soul, and his preoccupation with their affairs that has prevented him from perceiving that Soul.
The effect of the Ritual has been.
1. to keep them so busy with their own work that they cease to distract him;
2. to separate them so completely that his soul is stripped of its sheaths;
3. to arouse in him an enthusiasm so intense as to intoxicate and anesthetize him, that he may not feel and resent the agony of this spiritual vivisection, just as bashful lovers get drunk on the wedding night, in order to brazen out the intensity of shame which so mysteriously coexists with their desire;
4. to concentrate the necessary spiritual forces from every element, and fling them simultaneously into the aspiration towards the Holy Guardian Angel; and
5. to attract the Angel by the vibration of the magical voice which invokes Him.
The method of the Ritual is thus manifold
