Well, you do have a scrying mirror, everyone does.
A few months ago I signed up for Jason Miller’s Strategic Sorcery course, in one of the lessons he details the structures of our astral and energetic bodies. He points out that the area that forms a triangle between our temples and 3rd eye is a built in scrying mirror. Ever wonder why EA and S.V.E. use to stress that exercise of rolling your eyes up to look at your 3rd eye before evocation? Now I know why.
I had some time before work so I held a little scrying session, upon opening my eyes everything had a blue astral tint to it.
Enjoy, and get to work scrying.
