Hello. This method of evoking angels is not my own. I learned it from a teacher who has practiced ceremonial magic for many years. It is based on Hermetic Qabalah and the Tree of Life as a framework for calling upon different kinds of angels, whether an archangel or an angel. The angel you wish to contact does not have to belong to the Jewish tradition; in fact, this method can also be applied to angels from other grimoires. Likewise, no previous experience with Hermetic Qabalah or ceremonial magic in general is required to perform these evocations, I've already put this method into practice many times, and in my case, it works very well.
With that said, I'll explain the materials and conditions needed by using an example.
Let's assume we want to evoke the Archangel Gabriel. Gabriel is traditionally associated with matters of protection, the psyche, and various forms of divination, such as clairvoyance. In Hermetic Qabalah, the Archangel Gabriel corresponds to the Sephirah of Yesod. Yesod is associated with the Moon, and the qualities mentioned above are traditionally attributed to the lunar sphere.
MATERIALS:
\* 9 purple candles.
\* 1 moonstone, milky quartz, pearl, or any other stone or metal with lunar correspondences (such as silver, for example).
\* 1 black mirror or crystal ball (preferably made of obsidian).
If you do not have a black mirror or crystal ball, you may use a bowl of water instead. The important thing is to have something that can facilitate scrying.
\* Flowers such as jasmine, or a lunar-correspondence incense such as sandalwood, are also required. If you do not have jasmine, sandalwood incense alone is sufficient. The incense must be natural—it should \*\*not\*\* be synthetic. This last point is important.
The Sephirah of Yesod is traditionally associated with various symbols, deities, and both mythical and real animals. Since we are calling upon an entity associated with Yesod, it is recommended to include items traditionally linked to that Sephirah in order to establish symbolic affinity through correspondence.
For example, you could use a turtle figurine, as the turtle is associated with Yesod. You could also wear a necklace featuring the Moon or another symbol archetypally connected to the lunar sphere.
To make it easier to find the traditional correspondences of Yesod, I recommend reading Liber 777 by Aleister Crowley. There you will find the correspondences for Yesod, as well as those of the other Sephiroth and the paths of the Tree of Life.
Create a personalized sigil/talisman for the Archangel Gabriel. You will need to create a sigil and draw it on a sheet of paper, or preferably on a metal plate if possible. The sigil can be created using either the Lunar Kamea or the Hebrew Wheel of Creation. The method itself is not important; what matters is that the sigil contains symbols associated with Yesod.
My recommendation is not to overcomplicate the process, since the only essential requirement is that it incorporate the symbolism of Yesod, as well as the name of the god of the sephirah, the name of the angel or archangel, and the name of the choir.
PREPARATION
Before anything else, it is very important that, at the time of the evocation, the Moon is either waxing, full, or new. If the Moon is waning, the evocation will not be as strong, making it more difficult for the angel to manifest on the physical plane, or its emanation will be much weaker.
Once this first requirement has been met, the next step is:
Spiritual purification: In the case of angels or archangels, purification is not strictly necessary. However, if you are a beginner or new to ceremonial magic, it is highly recommended. Besides purifying your aura, it also helps you enter a trance state more easily. It is also said to eliminate unpleasant odors that might discourage certain types of spirits from appearing.
For purification, it is recommended to abstain from alcohol, meat, and sexual activity (including masturbation) for at least one day before the evocation. (I adopted this recommendation from the Ars Goetia.) As I mentioned before, purification is not as important when working with angels or archangels as it is when calling upon a demon, but it is still considered beneficial.
\*\*Choosing the planetary day and hour:\*\* For angels—and specifically for the Archangel Gabriel—we use Monday during the planetary hour of the Moon. (You can check planetary hours using a smartphone app, although in general the first planetary hour of the day usually corresponds to the ruling planet of that day.) Since the Moon rules Monday, we also perform the evocation during one of the Moon's planetary hours.
This principle applies to all archangels, and it should also apply to angels in general. For example, if an archangel's planetary correspondence is Mars, then the evocation should be performed on Tuesday during the planetary hour of Mars. If its correspondence is Mercury, it should be performed on Wednesday during the planetary hour of Mercury, and so on.
With all of this in mind, and after completing the preparations, we use the Divine Name corresponding to the Sephirah of Yesod, which is "SHADAI EL CHAI", followed by the name of the angel or archangel—in this case, GABRIEL—and finally the angelic choir to which he belongs, CHERUBIM.
For example, if we wanted to evoke the Archangel Raphael, we would use the Divine Name ADONAI ELOAH VE-DAATH, followed by RAPHAEL, and then the angelic choir MALAKHIM, which corresponds to the Sephirah of Tiphereth.
THE EVOCATION.
Assuming you have completed the purification beforehand (if you chose to do so, since that is entirely up to each individual), once it is Monday and the planetary hour of the Moon, prepare your altar.
Place the nine purple candles on the altar. They do not need to be arranged in any particular order. Light them, then prepare the incense or flowers. Place the stone with lunar correspondences, along with the talisman or sigil you previously created. Also include any objects or symbols associated with Yesod (such as the turtle mentioned earlier). Finally, set up the bowl of water, black mirror, or crystal ball for scrying.
Everything should be placed on an altar. The size and design of the altar are not important—you could even use a desk. What matters is simply that all of the items fit comfortably on the surface.
Once you have lit the incense (or arranged the flowers) and everything is in place, you may begin the evocation.
Steps for the evocation:
Visualizing the Tree of Life:
Close your eyes and relax your body. Visualize a purple sphere in your groin area; this symbolizes Yesod. Take your time to visualize it, and then visualize how this sphere expands to form a dome larger than your body, shaped just like the sphere.
Standing or sitting in front of the altar, recite the following out loud in a chanting tone, as though you were singing:
SHADAI E'L SHAI
Repeat a total of 9 times.
After repeating \*\*SHADAI E'L SHAI\*\* nine times aloud in a chanting voice, recite:
GABRIEL
Repeat a total of 9 times.
Then recite:
CHERUBIM
Repeat a total of 9 times aloud in the same chanting voice.
This completes the evocation.
After completing the invocation, relax your eyes and fix your gaze on the crystal ball, black mirror, or bowl of water. The purpose is simply to observe whether anything is revealed to you. It is important not to strain your eyes or try to force yourself to see something, as doing so may lead to self-suggestion. Simply relax your eyes, clear your mind of expectations, and allow whatever happens to happen. Whether you see anything or not is not important.
ESTABLISHING CONTACT WITH THE ENTITY
If you followed all the previous steps correctly, you may perceive the presence of the archangel or angel through sensations or manifestations. Some people hear ringing in their ears, while others experience visions. According to this tradition, this is because the angel's emanation affects the human nervous system.
In general, you should not be concerned if this happens, nor should you expect to experience the same things as someone else. Every person has a different experience, and the angel may manifest to you in a completely different way than it does to another person. This is commonly referred to as personal gnosis.
Now comes the process of establishing contact with the entity.
Whether you see the angel or not, whether you feel its presence or not, the entity is considered to be present (assuming all the previous steps were carried out correctly). Begin speaking to the entity. Introduce yourself, tell it your name, and ask it questions. Ask for its name—it may even give you a different name from the one you originally used to call it. Ask about its functions or offices, and ask whether it can help you with something you need assistance with, provided that your request is compatible with its traditional functions.
Once you have finished speaking with the angel, you should formally dismiss it and thank it for its presence. You may use a dismissal taken from any grimoire; it does not matter which one, as long as it serves as a proper farewell. According to this tradition, this is done so that the angel may depart. If it is not formally dismissed, it is believed to remain present.
Even after you have said goodbye, you may continue to feel the angel's emanation for a while. However, it will eventually fade, so there is no need to worry.
With that, this explanation comes to an end. If you have any questions about this method, feel free to ask. It is even possible, according to this approach, to evoke demons from the Ars Goetia using Hermetic Qabalah, although the process is somewhat more complex. In any case, if you have any questions about it, don't hesitate to let me know.
