Defensive magic

 
  Defensive magic is to ward away or cause danger to be somewhere else by trick or trade. For some defensive magic you don't change your physical expression, you change your auric expression. Possibly shifting the color could help, but not to a stereotypic one. If I want people to back the fuck off, I make my aura look a really evil shade of red.

  If you want to hide, make it a silver gray. Then back away and go another way to get away or to go and make them go another way by telling them to in your head which is shared into their minds or in their minds.

  Here's some idea of what will happen from someone who attempted the trick. "I did something similar, I told someone in the bus not to sit with me with my mind, he went towards me and somehow suddenly changed his mind and went off to the next seat." It turned out that I just look very angry when I'm in my 'neutral' mood/face. Some try to look fierce and it doesn't help, so to change your auric expression instead of your facial makes it work as a trick.

  Another, a thing to do would probably to learn how to flare and suppress your aura, which will repel hostility from you, or make you unnoticeable. I actually can flare both my aura and my resonance field to do this.

  All you need is to visualize the effect you want regarding people and beings, then combine that with a visualization of your aura flaring like a burst of energy or suppressing like you are fading away. To reverse it, visualize it going back to normal. My personal method is to tell someone to not sit near me and flare near him to cause him to back away.

  Here's a ward spell that is pretty easy, and effective for keeping beings, physical and not, away from you or places/objects you need to protect. Focus on the emotion or the idea, in this case, the feeling of wanting no one to go near the target, and make this feeling very strong. Focus on the target afterwards and pretty much everyone will stay away.

  This effect will either last for an unlimited time or end when you are dangerously low on energy (below 5% normal capacity), as it needs the energy from the caster to be maintained. It could be altered to make it so it doesn't need your energy, but maybe energy from the surrounding environment, which there is a lot of in most cases, but I've only tried this with areas I want privacy in.
