Below, are two examples in which to do mirror scrying.
Using a mirror as a scrying plate
A mirror is placed flat on the table, or you could have it at a 90 degree angle, this is to avoid seeing our own reflection in the mirror. A small candle or light is placed near the mirror, close enough to allow the light to reflect onto the surface of the mirror. Either put the candle behind the mirror, or you could have one at either side.
Sit quietly and pay attention to your breathing and when you are ready, open your eyes and gaze into the mirror, remain relaxed and don't forget to blink when necessary! After a while the surface of the mirror will begin to change and fade, a mist may appear and your third eye, or inner eye will open and the journey now begins.
What you must remember is the inner eye sees inside of the mind, Most people when scrying do not see the images with their physical eyes on the mirrors surface, but within the mirror and in the minds eye. The mirror acts as a focus point, a gateway to within.
When you have completed your journey or work that you set out to do, begin to return to yourself and your body and its senses. Be aware of your breathing and breathe fully and deeply whilst remaining still until you have completely returned to the room. Think on your experiences and write them down in a journal. I cannot stress how important writing down your experiences are!
To stand before a mirror and stare into your reflection.
The start up will be the same, create your sacred space, making sure that you are not disturbed by noise or outside influences. Extinguish all lights apart from a torch held slightly under your chin. When you relax your vision, images will appear in the reflection. You will begin to see your features change shape, and keep changing. Some say this is past lives, or who you are in a parallel life. For more information you could try using a candle instead of a torch, and read the wax that falls after your journey or messages. * please use the candle safely and tie back hair and loose clothing to avoid becoming an inferno!
Keep your Mirror clean, use a soft cloth and alcohol or similar.
Only use it for its intended purpose, It is, after all, a sacred tool.
Store the mirror away when it is not in use, you could use a dark bag or wrap it in black silk.
Avoid letting other people handle or use your mirror, we wouldn't want anyone else influencing what you see.
Allow nothing to reflect in the mirrors surface, it should appear as a dark window.
Keep a journal and record your experiences.
Scrying is best at night, the most favourable times would be New or Full moon, depending on your intention.
