This spell calls upon Abaddon to manifest poor mental health in the mind of your enemy. It manifests bad mental health directly as well as manifests painful events for your target to compliment the change—both effects are fast-acting, but the former is faster. If this spell is performed over the same target four or five times, the effects can be long-lasting or even permanent.
All you need is a black candle, emotional pain, and hatred. If you intend to perform the rite over the same person repeatedly, it won’t matter whether you re-use the same candle or use a new one.
Light the candle and focus upon your pain, your hatred, and your intent to make your target suffer mentally. Channeling that emotion and intent, chant Ovgara Dyz Gavak over and over again for as long as feels right to you—a few minutes will suffice.
Make sure to thank Abaddon every time that you do this, and it would’t hurt to give him an offering.
