HOW TO SCRY WITH A BLACK MIRROR
PREPARE YOUR SPACE AND GATHER YOUR TOOLS
It is widely believed that it is best to scry at night as the practice is closely tied to the energy of the moon. Plus a calm, dark night is perfect for focusing as there are fewer distractions around. Whether you are inside or outside, it’s best to find a dark, quiet place with as little light as possible. 
Make sure you have your scrying mirror, candle, and if you’d like to write about your experience, a journal and pen. Light your candle (and some incense if that’s your thing) and place it out of your direct line of sight but where it is still visible on the surface of the black mirror. Some prefer to place the candle immediately in front of their mirror or even stare directly into the candle flame. Try different places and arrangements to find what you like best.
START WITH A BREATHING EXERCISE OR MEDITATION
Next, settle into a comfortable seated position and begin to focus on your breath with your eyes closed or open. In and out. In and out. Each time try to breathe more slowly deeply filling and emptying your lungs. Let the thoughts of your day and to-do lists drift away. It’s okay if they come back, let them move across your mind's eye and drift away again. (As I said, this will take some practice and your first session isn’t likely to be perfect.)

PEER INTO THE ABYSS
You may at this point begin to feel a sense of calm and relaxation that indicate you are entering a more trance-like state. Now it is time to focus your gaze upon the Obsidian scrying mirror. If your eyes were closed, slowly open them. If they were already open, shift your gaze to the inky black surface.
Maintain a soft gaze that allows the mirror to remain just slightly out of focus. Keep an open mind and make a mental note of whatever ideas, flashes of inspiration, or objects come up for you. It’s okay to not understand them in the moment, you can revisit them later.
When you’re first starting out try to maintain this state for at least 15 minutes. As you grow more comfortable, you can scry for longer periods which may allow you to reach further inside yourself and gain greater insights.
END YOUR SESSION
When you’re ready you may end your scrying session. There are no rules or guidelines around how you may choose to end your session. I personally like to close my eyes and say ‘it is done’ before blowing out the candle and slowly beginning to move out of my seated position. Be careful when getting up or moving around afterward to avoid tripping in the dark or feeling light-headed.
If you have a  journal and a writing tool, write down what you saw or any thoughts that came to you during your scrying session. It’s best to write things down while your thoughts are still fresh.
