I've read about summoning demons by meditating on their sigils (without Angels and triangles). Is this also applicable to Pagan Gods? What is a good way to make their sigils and what should I draw them with? If I wanted to make a sigil for Cerridwen, should I arrange ogham letters into a symbol after removing repeats, or would the number grid method work better? Also, has anyone had any luck evoking gods into a triangle CM style?
