First, you need to cast a circle. If you don't know how to do this, then Google it. You can use a wand to help control your energy. Place an item in each direction of the circle as you call the elements and invoke the God and Goddess. You can use salt to purify your circle by sprinkling it around the perimeter. Now that all of that is done, we can begin the spell.
Sit in the center of the circle, staring down at the photo of yourself. All of your ingredients should be inside of the circle. Light the white candle and sit it next to the photo. Say:
"Humanity, Humanity, inside of my soul. For you, I have paid the ultimate toll. My humanity is like my life- It is like a flame. But I am tired of this boring game. Everything is always the same."
Pick up your athame/knife and hold it above the photo of yourself. Say:
"I no longer want to live or ever tire. I want to die and be reborn. Not as a human, but as a vampire." Stab the photo of yourself with the knife and then pick up the dirt and sprinkle it over the photo. Say:
"With this dirt that is part of this world. May my humanity be buried and never return. There's no going back from this new torment. No longer shall I know humanity. No longer shall I live like others. No longer shall I breathe or eat. I thirst for blood. I live for blood. I breathe for blood. Gods and Goddesses, please fulfill my transformation."
Pick up the needle and prick your middle finger (it hurts less on this finger) and then use your blood to put out the flame. Say:
"I am reborn. The transformation is complete."
Drink the rest of the blood from your wound and then clean everything up. It is best if you do this before bed. The transformation differs from person to person. Okay, hope this spell works for you. Blessed Be )O(
