From Yoga Journal, an essay on "The Heart's Intention"
Setting intention, at least according to Buddhist teachings, is quite different than goal making. It is not oriented toward a future outcome. Instead, it is a path or practice that is focused on how you are "being" in the present moment. Your attention is on the ever-present "now" in the constantly changing flow of life. You set your intentions based on understanding what matters most to you and make a commitment to align your worldly actions with your inner values.
Goals help you make your place in the world and be an effective person. But being grounded in intention is what provides integrity and unity in your life. Through the skillful cultivation of intention, you learn to make wise goals and then to work hard toward achieving them without getting caught in attachment to outcome. As I suggested to the yogi, only by remembering your intentions can you reconnect with yourself during those emotional storms that cause you to lose touch with yourself. This remembering is a blessing, because it provides a sense of meaning in your life that is independent of whether you achieve certain goals or not.
