This habit is best practiced with small things first, such as a dog barking, children screaming, or even a traffic jam. With practice, you will be able to destroy that wall of resistance inside of you that tells you that “this should not be happening”. Then, you will no longer feel those negative emotions.
Imagine your body becoming transparent.
Allow whatever is making you feel negative emotions to pass right through you.
For example, if there is a loud noise such as a car alarm irritating you, imagine that noise passing right through you.
