Vishen Lakhiani argues your best boundary tool is your feet. Leave situations that feel wrong without needing permission or explanations. Don't waste energy trying to educate the person who upset you.
Chapters
The biggest boundary protecting element you have is your left and right foot. If you are experiencing being in an energy that doesn't feel good to you, you have to give yourself permission to walk away. Now, you don't have to get the permission from others, nor do you have to explain. All you have to do is say, oh, I don't feel good, I gotta go, or oh my God, I, I don't know what's wrong, I need some air. You don't have to say you're a toxic, abusive person and I have to run away from you. That's too much information. You just excuse me. Gotta go and walk away. It works. It empowers you internally because your boundary is your responsibility to enforce, not to push someone back, but to remove yourself from from energy that's incongruent or not good for you. A lot of people make the mistake with boundaries that we have to educate the other who is offending us as to why they're so offensive. You're wasting your time. They might consider you just as offensive, by the way. So take that out of the equation and just understand this is not a vibrational congruency. Doesn't feel good, I gotta go.
