Okay, so I had actually had this as a blog rough draft for quite some time now... so, here it is.  My apologies in that it had not been posted sooner.  This is the format in which I had used, which is partly instructional should you wish to do something similar.

The Methods

1. Creation of the Sigil. As mentioned in the companion thread, I'll be constructing a sigil from the Rosy Cross method. This is a digital representation of the name of the elemental being created and it's sigil. Generally speaking, one should not give out the name/sigils of their personal spirits, unless it is to propagate their presence beyond your domain. A Magician who dislikes you could *easily* destroy your young servitor by using its sigil. "Be Silent."

Above is the Hebrew and it's English Transliteration of the Rosy Cross. Constructing a sigil from the icon is as simple as beginning with a circle on the first letter, tracing it to the next, then the one to follow, terminating the last letter of the spirit's name by crossing the end of the line. For example, let's say I was going to call it Ralph:

Moving on from this simple demonstration to the rest of the ritual. Remember, with this method you will need TWO COPIES of the sigil, and those copies must be exactly identical!

2. Prepare your altar. Have your the physical host, from which your elemental will be "installed", your candle and your sigils placed upon it.

Timing for ritual? It's up to you. If you decide to construct a sigil from the planetary kamea, you may wish to do all of this within that particular planetary hour. You'll likely wish to invoke that planetary power, too, in your ritual.

3. Banishing rituals. I would recommend, minimally, the Lesser Banishing Ritual of the Pentagram. You may wish to include the Lesser Hexagram formulae, too, to effectively banish and consecrate the temple space.

4. Invoking rituals. The Invoking variant of the Lesser Pentagram formulae alligns and invokes the Higher Self. I'll be doing this and Liber Samekh, to firmly establish the Authority of my Higher Self over the rest of the ritual.

5. Use a passive tool that is emblematic of your Will; the Wand or the Cup, notably, may work better than the athame or the Sword. The Disk, also, may make do. If you have nothing else, your dominant hand will work just fine. Point the tool at the sigils and begin to direct life-energy into it, through the medium of your Higher Self. Focus exclusively on the task. Give your elemental form and figure, if you will; it may look just like the host into which it resides, or it may be abstract. You are now binding that thought-form into that sigil. That sigil then, and any reproductions, will be your gateway to that particular entity. It's a geometric form of its very existence.

6. Now, affix one of the sigils to the bottom of the host. I recommend making it removable, so a pin, tape or a bit of glue works well. It seems a bit tacky, but if you ever want to reverse the process, or move it to another host, it's easier if you can just detach the sigil from it. It will have weight on it from the statue/doll/etc anyway, so it shouldn't detach easily.

7. Now, let's bring the creature to life in the host. Using my nutcracker, I can access all of its relevant anatomy through the method that I am using, developed from Sefer Yetzirah. Using to the letter-anatomical association chart below, touch and direct energy into the locations while vibrating the hebrew letter. We're emulating the process of creation according to the Book of Creation. For citation purposes, I am using Kaplan's translation.

ALEPH: Chest

MEM: Abdomen
SHIN: Top of Head

BET: Right Eye PEH: Right Nostril

GIMEL: Left Eye RESH: Left Nostril

DALET: Right Ear TAU: Mouth

KAF: Left Ear

HEH: Right Hand LAMED: Liver

VAU: Left Hand NUN: Spleen

ZAYIN: Right Foot SAMEKH: Bladder

ChET: Left Foot AYIN: Intestines

TET: Right Kidney TZADDI: Stomach

YOD: Left Kidney QOPH: Throat

8. Now, upon directing more life-energy into your servitor, hold it up, breath upon it, call its name and give it purpose. Make sure you define it very clearly. You may wish to speak something like:

"I welcome you, spirit name , and, as your Creator, hereby give you this specific task: That you should protect and defend this home and its inhabitants, from any assault directed as me/us from any source, visible or invisible, and that you shall always be alert in doing so. At no point may you perform any other task aside from this one, and when called to assist, that you should come without hesitation. As this is your job assigned from your birth, so shall it always be."

I then "sealed" it with the invoking pentagrams of active and passive spirit above my elemental.

9. Light your candle. Place the duplicate sigil beneath it. The energy from the flame will feed the elemental. Other ways of "feeding" the spirit, through the sigil, may be devised and is left to the discretion of the Magician. It may be helpful to have this candle consecrated, too, for the specific purpose of giving life. In either case, do not use the candle for any other reason. Allow the energy to feed your servitor for minimally an hour-- all the better if you let the whole candle burn through and replace with a new one.

10. Place your spirit on a high shelf or other fixture whereupon it may stand without risk of being knocked over by accident. Because of the proximity of the kitchen to my front door, mine is sitting on top of the refridgerator and facing the door. Since it's still near enough to where I perform my practices and facing the likely entry point of which an intruder would enter, it's quite perfect.

You should make a committment of occasionally "feeding" your spirit through energy exchange. Any energy directed should be through the sigil or, through the spirit's host directly. This keeps your elemental strong and capable of standing to the task in which it was created. Forgetting about it early on may mean it's fading out and return to your consciousness. Later, it's possible that it could be frustrated and do things to try to get your attention.

If you find that it has been knocked down without reasonable explanation, it is possible that it has taken a "hit" for you from some direction. You'd naturally wish to divine (or whatever) to decide from whom or what it came, but you'd also wish to recharge your spirit immediately, too.
