This one’s going to be really brief.
When you have someone in your life that’s trying to attack you psychically, physically, emotionally or mentally, you can either bind them or banish them.
Binding them will stop the attack. Whereas Banishing them will remove them from your life altogether.
Either is fine, as long as you make sure you aren’t performing the act for personal gain or as a matter of trying to control the other person. Those are no-no’s.
