Over our various lifetimes, we may give away or take soul pieces to or from another, leaving us incomplete, or holding onto something that is not ours.
Both soul retrieval and return are mediated by our spirit guides.
When we discover that we have soul pieces that do not belong to us, we simply ask our spirit guides to return them to whom they belong.
Verify that the pieces have been released. If we are still holding onto them, address any stuck energies that are preventing us from letting go.
