The Sign of Horus - Take a step with your right foot and thrust the hands forward as you forcefully vibrate a name. This sign is normally used as an aid in charging sigils drawn in the air. Can be used in the Lesser Ritual of the Pentagram to charge the drawn Pentagrams with energy.
The Sign of Harpocrates - This sign almost Always follows the Sign of Horus to cut off the energy current that was being sent forth while charging sigils etc. Simply return to a normal standing position, and point the forefinger of the Right hand at the lips (as in Egyptian art depicting the god Harpocrates- Horus the child, a silent god).
The L.V.X. Signs
L.V.X. (lux pronounced lukes) signs shown in order.
The Sign of Osiris Slain - Make a cross with your arms. A symbol of the dying god who is later resurrected. (Osiris pronounced Oh-Sigh-Riss) Death/crucifixion I. of I.N.R.I. Winter
The Sign of the Mourning of Isis - This version differs from that of the original G:.D:., however I found it an interesting varient. The idea is to create a human swastika of sorts (no not a bad symbol- representative of a whirling force and resembles the letter aleph). The edge of the right hand is facing forward as if to chop something. The palm of the left hand is facing behind you. The arms are in the angles shown, neither ahead nor behind the body (a swastika is a flat image). The head is looking down over the left shoulder. A new whirling force coming in-Spring. N. of I.N.R.I.
The Sign of Apophis and Typhon - The arms behold the sky while the head is thrown back. Summer. R. of I.N.R.I.
The Sign of Osiris Risen - Cross the arms about the breast and bow the head. Fall/harvest Final I. of I.N.R.I.
The L.V.X. signs go along with the analysis of the key word I.N.R.I. which turns into IAO (pronounced EE-AH-OH). IAO can be thought of as representing the processess of Creation (I), Destruction (A), and Rebirth, or reconciliation/continuance (O). I favor the latter- continuance, since Creation and Destruction are merely 2 sides of one phenomenon with no in-between being represented. Between the times when something is being created or destroyed, there is an in-between state where things are being preserved until the next episode of destruction and creation/rebirth.
If it isn't obvious by now, performing these signs while in a ritual format will cause you to remember what they are symbolic of provided you have meditated on the topic.
The Portal Signs
The Rending of the Veil (no picture available)- This sign is more of an action than a living symbol. To perform, stand normally and extend the hands in front of you with palms turned outward as if to spread open a veil or curtain. Then, part the imaginary curtain (make the motion in front of you). Spread the imaginary curtain wide enough to walk through, but don't step forward (unless the working requires it). This sign is usually performed when one wishes to open a link or portal to another plain. Sometimes called the Active Sign of the Portal.
The Closing of the Veil (no picture available)- This sign is also more of an action than a living symbol, and is used together with the Rending of the Veil. To perform, extend the hands in front of you with palms facing each other as if to close a curtain that was opened wide enough to walk through. Then, close the imaginary curtain (make the motion in front of you). This sign is usually performed when one wishes to close a link or portal to another plain. Sometimes called the Passive Sign of the Portal. In a working, you would use the Rending of the Veil to open a portal, and when you're done working with that portal you would use the Closing of the Veil to seal it back up. Both Signs should feel very natural to perform, as they are motions similar to what you would use if you needed to enter or exit a room that used hanging beads or curtains for a door.
Zelator (1=10) refers to Earth
Theoricus (2=9) refers to Air
Practicus (3=8) refers to Water
Philosophus (4=7) refers to Fire
Above are the elemental grade signs as used by the Golden Dawn. Water and Fire signs are almost identical in hand positioning, only the arm positions have changed. These are the signs used in the Supreme Invoking Ritual of the Pentagram (which makes some use of Enochian forces).
