There is nothing set in stone regarding an effective working. If there were, it would be that sufficient adrenal and emotional energies, fused with vivid visualizations are needed for maximum magical power, but that's it.
It is important to remember that all religious forms, images, invocations, ceremonial trappings, etc., were created by human beings, and can of course be altered to suit your personal tastes. The Satanic Bible gave a basic model, but was in no way the final authority of what an effective working should consist of. That authority and power rests in you.
