Gradually over time as you recognize more clearly who is responsible for doing what to whom, and that all attack is self-attack, you will start noticing that other people's attacks are not really attacks.
Their attack, is not really something which connects to you, bridges a gap between you, or leaves the other person to come into you.
Instead, you will start to get this idea, or simply to notice, to recognize, that although they are TRYING to attack you, it isn't actually attacking you.
If you recognize the person is the one "under attack", and that it's not really about you, you can choose not to USE IT to attack yourself. You can choose not to participate.
Deciding not to participate in their attempted madness makes it possible for you to be present and loving in spite of their attack, to see them as innocent and guiltless, and to offer healing.
Someone could be ranting and raving right in front of your face and, somehow, it's not about you. They're the one who is in pain or calling out for love. It's their expression. And their attempted attack doesn't necessarily have to have any effect on you.
When you are more in-tune with being causal, taking responsibility for what you experience, and knowing that you can only be hurt by yourself, this just becomes clearer and clearer.
This is the beginning of invulnerability and a step towards your immortality and permanent peace.
