Is there any benefit to doing this for specific workings? Like a cube shape for self-control/habit changes/discipline for example.
I remember when I first joined I instinctively made my AoP aura into a sphere, like sitting inside a huge golden Sun and it felt quite good to me to do, intuitively.
When I do the scanning method for aura cleaning, I also use a triangle projector shape.
Or God Rituals, I imagine 3-points between: me, the sigil, and the universe above, all connected in a triangular shape as I am vibrating the runes.
