The period of completion, rather than being just an act of finality, is also one of transition.
The period of completion, rather than being just an act of finality, is also one of transition. When we seek closure, what we really want is an understanding of what has happened and an opportunity to derive what lessons we can from an experience. Without closure, there is no resolution and we are left to grieve, relive old memories to the point of frustration, or remain forever connected to people from our past. A sense of completion regarding a situation may also result when we accept that we have done our best. If you can't officially achieve closure with someone, you can create completion by participating in a closure ritual. Write a farewell letter to that person and then burn your note during a ceremony. This ritual allows you to consciously honor and appreciate what has taken place between you and release the experience so you can move forward.
Closure can help you let go of feelings of anger or uncertainty regarding your past even as you honor your experience  whether good or bad - as a necessary step on your life's path. Closure allows you to emotionally lay to rest issues and feelings that may be weighing down your spirit. When you create closure, you affirm that you have done what was needed, are wiser because of your experience, and are ready for whatever life wants to bring you next.
