When we speak from our hearts, there is no right and wrong. If I tell someone else she is wrong, I am probably either not hearing what she is saying or I am not accepting it. Instead, I am judging, externalizing, or defending. When I tell someone else he is wrong, it is usually to elevate my position or to avoid taking blame or responsibility.
When I consider myself wrong, I am not respecting my own truth. I take the power away from my heartvoice. And I may be enabling somebody else by taking blame or responsibility for him. I disable that person from taking personal responsibility for his actions. In doing so, I give him power over me, while at the same time I self-deprecate and disempower myself.
Why would I do such a thing to myself, or to another? I may have low self-esteem, and it may be a sign that I am in an abusive relationship (the two usually go hand-in-hand).
In healthy relationships—both with self and others—the concepts of right and wrong do not play into relationship dynamics. When we speak from the heart, what is, is, with no qualification. Each of us hold and speak our own truth, take personal responsibility for our words and actions, and respect the truth of the other, no matter what it is. When we do so, we create a supportive, healing environment seeped in acceptance and understanding.
