"There is a vitality, a life force, an energy that is translated through you into action. And because there is only one you in all time, this expression is unique. If you block it, it will never exist through any other medium: the world will not have it. It is not your business to determine how good it is, nor how valuable, nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open."
