To understand non-attachment, you must first grasp the opposing concept of attachment. Take this example: You’re training for a half marathon with high hopes of running a personal best. This is somewhat of a stretch goal for you, but you feel that you’ll be able to achieve it with training and commitment.
To better your chances, maybe you hire a coach, subscribe to an ambitious training plan and clear your schedule for training to be a top priority. All is going well until a couple months into training when you feel a minor pain in your knee during a run. Instead of slowing down to inspect the issue, you continue to push through the workout because you know it’s a key training session.
Later that evening, you find yourself limping and in pain, but even still, you run again the next day and the day after that. You’re terrified at the thought of skipping any training for fear that it will derail you half marathon goal.
