The process sounds simple, and it is. Ask a question. Stop. Wait for an internal answer.
The mind will want to give a fast answer, let that pass. A richer response will come internally. Sometimes it comes as an abstract shape, color, sound or sensation. Let the response move, until it has words. You'll know that you have the internal sense of truth if, when you speak it, you feel an opening, relief, or pleasure in the body. You might find yourself sighing, or taking a deeper breath.
Often, it helps to have another person present while you focus. The other person is not there to answer anything, or provide insight. A good focusing partner will just help you keep your attention on the current question. Patience and an ability to keep a kind, neutral openness to whatever arises makes for a good focusing partner. Maybe you have a friend or family member who already does this for you. A person who knows how to listen is a gift.
We probably don't need to drop into a focusing moment to decide what shoes to wear in the morning. However, if you are feeling the pressure of something niggling in the back of your mind, or you have a decision that you have analyzed to the point of no return, or a need for wisdom in connecting with another person, consider giving focusing a try. Your truth may surprise you.
