Working with sigils

In a martial art for self defense that I studied, we practiced mind awareness. As we have usually used hard focus, where we concentrate out sight on a particular item, there is also soft focus, where the field if sight is pulled inward.
Example … You are walking down a city sidewalk, and windows line the street. At The end of the sidewalk is a dead end street. To use soft focus is to see everything, window reflection and what’s straight ahead. The hard focus is to have tunnel vision.
When using a sigil, I stare at it, let my vision pull back still concentrating on it, let the lines blur, or flash. I have up to that time been chanting the name, and let the presence be felt.
