it has 3 Sacred names of God - Tetragrammaton, Primeumaton, and Anaphaxeton one on each side and it has the name Michael (Archangel Michael) which is split into 3 sections MI - CHA - EL. This contains the spirit from escaping and compels them to obey. This does not mean in every case they are going to obey you... but it helps the process. Some Magicians would use Fresh Blood of a Sacrificed animal in the Triangle to attract the Demon. For Blood is the Life force and Demons thrive on it. Crowley would Sacrifice three white doves and pour the Blood into each corner of the Triangle... the Demon would stay until the life force was exhausted, then Demon would leave. This is not something for you to be going out and trying. Those of you whom are reading this are not the experienced and you would only end up possessed or Dead. This is just for your interest and thirst for knowledge. 1. You can trace it on the ground in dirt or sand. This is not the greatest way to do it. 2. You can make one out of wood and and paint it. The Triangle and the letters should be black along with the black circle in the middle of it. The interior should be white. You can do it differently if you so choose The choice is yours. With this method you can set it on the ground and take it with you when you are done with your Magical operation. These two methods are good for if you are trying to Conjure the Spirit into the Physical. How big should it be? The best dimensions would be 36"x36"x36". 3. Now... the other method is for Conjuring the Spirit into a Crystal Ball that is placed in the middle of the Triangle or using a Black Mirror in the middle of the Triangle. With this method... one Conjures the Spirit.... but one must Skry or see onto the Astral Plane where then Spirit is. The Mirror or Crystal Ball only acts as a focal point. You can set up the Triangle on a small round table and place a Crystal Ball in the middle or you can prop up the Triangle so that it is standing up and Gaze into the Black mirror... Once again... you must be able to Skry or should I say, have Astral Vision... that is... to see onto the Astral Plane. Those whom have not developed this ability will have no success. This takes much practice of Crystal Gazing or Skrying with the Black mirror which is something you can do without conjuring any Spirit and develop your Astral Vision and Psychic Senses.
