Defensive Spells

Chakkaa-Chakkaa spell: Purple light - causes the 7th charka to open 
and propels the persons spirit out of the body temporary, say for 5 
minutes while you run away. They are not able to use their wand or 
do any non-verbal spells without a wand, when in this state.

Agappa spell: Pink light. Hits the heart and causes them to feel 
love and compassion for you, for the next 10 minutes. Again giving 
you time to get away.
