The ritual she went through opens the gates of atonement for her, leaving her in a higher state than she was originally. Today, we don't have a Bais HaMikdash, but when we do, things will change. TOday things fly at you from every direction and often you don't know what to make of them, and how to let them change you positively. When moshiach comes, and the Bais HaMikdash is rebuilt, the rectifications that you need will be so clear that you and I will no longer need atonement, and the sin offerings will be substituted with thanks giving offerings.
