All of us who seek to be conscious and aware regard our experiences as teachings and we seek to discern what lessons we are learning from the experiences and relationships in our lives. Sometimes the lesson is very clear and other times we must really search to understand the deeper meaning behind the experiences.
While this search often yields results, there also comes a point in the search where what we really need to do is just move forward. It is possible that we are not meant to know the deeper meaning of certain occurrences. Answers may come later in our lives, or they may come as a result of letting go, or they may never come.
We are all part of a complex system of being, and things work themselves out in the system as a whole. Sometimes we are just playing a necessary part in that process with a result larger than we can understand. It may have very little to do with us personally, and while that can be hard to understand, it can also free us from overthinking the matter.
Sometimes it is best to see it in terms of karma, a past debt we have been able to repay in this way, or as the clearing of energy. We can simply thank the event for being part of our experience and let it go. This completes the process that the occurrence has made possible.
