I love the inverse tree which means you start from the Ajna; since that is your root into the world. It is up there somewhere in your forehead, and gives you perspective. If you have no idea where to start, then start with creating clarity through perspective. When you have that you will know better where / how to heal. I find a Heart centered practice is a good place to start in general, where you rest your attention in your Heart, and let it fill that empty void of silence with beauty and wonder - a place of true healing
