This requires a lot of time and patience.
You need three candles: white, light blue, and black. Black absorbs negative energy and dispels them harmlessly. Blue creates a calming effect, and white is used for peace.
Set the candles in a triangle. By nature, the triangle is the strongest form. This spell not only creates peace, but helps you feel stronger emotionally, and perhaps physically. It varies, even for myself, the spell caster. Light the candles, and sit in a comfortable position. Close your eyes and picture your favourite place, object, or person. Breathe deeply, and exhale slowly. Once you feel calm, speak this spell aloud, as many times you find needed.
I calm my mind and slow my breathing.
I feel the anger and stress all leaving.
Peace will come and take their place.
Tomorrow will be a better day.
Blow out the candles. Tomorrow will be peaceful.
Since this is my spell and not your own, it may or may not work. I hope this works as it has for me.
