Feeling is freedom
Living a life of choice does not mean you can switch from despair to joy in a heartbeat. Whether that is even possible or useful is up for debate.
Choice is the willingness to meet yourself exactly as you are and where you are right now from a place of compassion and love without judgment, attachment, or aversion. It is the discipline to be in your body and notice all you are feeling without any need to suppress it, run from it, or avoid it. It is the courage to feel the bigness of life.
You cannot control the thoughts or emotions that emerge in your experience, yet you can decide that you will meet all of them with as much grace as possible, knowing that grace will eventually lead you toward the good stuff.
You are free when you let yourself feel.
