Our things are not our emotions or memories. However, we often connect them. For example, items in our home cue memories and feelings and remind us of things we want to do. Learning to separate the two is an essential practice on your decluttering journey.
First, it's a practice and new habit to start noticing the memories and emotions connected to the items in our homes. Start by observing and perhaps write in your journal about your observations.
The next part of this practice/habit is recognizing that the memory and emotions are separate from the objects.
Finally, acknowledge that you can manifest what you need within yourself.
For example, if you notice difficulty when decluttering kids' old toys or clothes, note the difference between these objects and the beautiful moments you had with your loved ones. You aren't letting go of those lovely moments by letting go of these items. Instead, you are allowing another family to have similar moments with them. If you have a grandchild, trust that you will be able to borrow or buy similar items when it's time.
The true beauty of the experience is something you possess. It's your caring and the love you share with your loved ones. It's about spending time with them and sharing that love. This ability and experience are what you are keeping, and it's what you can manifest or bring about again.
