Peace comes from the heart not head.
So if I want to have peace I need to settle things of the heart. I need to look at my relationship with myself and also with others. Deal with the issues I need to deal with. I know what they are. I do not owe anybody an explanation about my actions. I only own myself the truth.
I should not seek attention and worry what people think of me. I should not worry about other people and be manipulative but sort my own self out.
If I can settle all the matters of my heart and when my heart and mind can hold hands and I am able to have some understanding and respect of others then it will be easier for me to let go. This is the path to peace.
Peace comes when I am able to let go.
