If you doubt yourself stop right in that moment. Say, stop, stop, stop to yourself. The repetition will help. Remember that our mind has what it wants to say. Your heart has what it wants to say and so does your body. Your heart is where you should head to. Sit still. Place your hands in your lap. Close your eyes. Breathe. Just concentrate on your heart and stay there for a few moments. Remember linear time is different than spiritual time so “take the time”. If you don’t, nobody else will. Just go with the flow and I’m sure you will feel better.
