From The Secret Daily Teachings
You cannot bring what you want to you if you are feeling stress. Stress or any tension at all is something you have to remove from your system.
You must let the stress go - it is the only way you can bring what you want. The emotion of stress is saying strongly that you do NOT have what you want. Stress or tension is the absence of faith, and so to remove it all you have to do is increase your faith!
