Take revenge against him. Develop decent amount of concentration and a strong aura of protection and do a runic destruction working against him. You should never be terrified of someone. You are not weak. He is the one weaker than you. You are superior to him and have no reason to feel weaker or inferior to him.
You cannot live in fear. You cannot live in doubt.And you cannot live in self hate..
Remember this line always.
Use a runic combination of THURISAZ, HAGALAZ, and ISA.
Do some kundalini yoga and start feeling that buzz of energy . Then go into a decent trance and FEEL those feeling of Hatred and that INTENT to inflict PAIN and Suffering. Fully get into that feeling and visualize him getting hurt,inflicted with pain,hit by a car, anything that you want to hurt him with .Start vibrating the runes *54 times each and then state the affirmation.
Vibrate THURISAZ x27 (or a multiple of 9) and then affirm x9 "The energies of Thurisaz are permanently and completely destroying (name of individual)." Vibrate HAGALAZ x27 (or a multiple of 9) and then affirm x9 "The energies of Hagalaz are permanently and completely destroying (name of individual)." Vibrate ISA x27 (or a multiple of 9) and then affirm x9 "The energies of Isa are permanently and completely destroying (name of individual)." You can then visualize the individual being destroyed in any way you please.
This is from Johson Akemis Satanic Faqs.
After letting all of that hate and energy transferred to him and affirm,clear your mind completely (hence why void meditation and concentration is required.)
Then vibrate VISSHUDHI *11 into each chakra and then *31 times into the Aura for Aura cleaning. Take some time to visualiaze your aura and chakras completely clean from any kind of negative energy.
Its time to hurt him back like he hurt you. Instill absolute dread inside of him and make him pay. Convert that fear into seething hatred to take revenge. Never let anyone who hurts you off the hook. You play fire with a flamethrower with propane. If someone uses bullets, you use a rocket launcher. If someone uses a rocket launcher you use a nuke. Satanists never take abuse, especially when you have a legitimate reason to take revenge .
