Allow the loss. Allow the sadness. Allow the hurt. As you allow yourself to feel your hurt, the hurt loses power and begins to dissolve. When you fight and resist your hurt, the hurt turns into pain and seems to last forever.
Little children are masters at releasing hurt.
This is because they are totally willing to feel their emotions. When they feel hurt, they cry. When they finish crying, their hurt disappears. They bounce right back as though nothing had ever happened. So be like a child.
