For anyone who can answer: When Bardon talks about directing causes from the mental to astral planes,there is mention of the fact that the 2 letters must have a shape. The color of the shape could be of several interpretations of the text. 1. Each letter is plasticized into its own independent shape and independent color in sequence. OR... 2. You have to imagine a shape that is somehow a combination of the two colors ( in stripes, patterns, or a completely mixed pallet ), and the tones are mixed together (as in a musical chord). Which of the 2 choices is the correct interpration of plasticizing with a two letter key? Regards, Barry Solomon
