Should detachment, and letting go, be an appropriate response when you are owed money?
Imagine a monkey came to your house and grabbed something of value and climbed a tree. You tell the monkey "please give it back to me! Be a good monkey!". But it doesn't respond. What would your plan of action be? Start cursing and hating the monkey? No! You would try to lure the monkey with a banana or something. If that's not successful, you might call a wild life officer. You have to use your wisdom instead of getting all emotional. And if you still can't get it back, you don't wish for the universe to resolve it. ex: Wishing for the monkey to be struck by lightning. :) You just let it go and credit it towards experience or a lesson learnt and see what you can do to prevent the same from happening in the future.
