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.- lessons from The Secret
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 that in every single moment the Universe is unfolding precisely as it must in its constant process of delivering whatever intention you've declared for yourself.
Classic example: Can't find your house keys. Don't get angry, upset, and stressed-out (i.e, "I strongly feel I do not have what I want! And, what's more, I want the whole world [Universe] to know how upset I am!"). Equally unproductive, don't go into victim mode and say or think self-defeating thoughts like, "I'm so forgetful," or "I'll never find my keys." Remember, for the Universe "your wish is always and instantaneously my command." Be careful with what you think, declare, and what type of energy you are "broadcasting." Once a person has chosen to dive into the nightmare of an anger-and-victimhood "rabbit hole," it could take a while for him or her to emerge back into the sunlight. If ever... Sadly, some people spend entire lives lost in dark mental tunnels. Tragically, some have even forgotten what sunlight is or that it even exists.
Perhaps, a better approach when faced with a challenge is to simply declare an intention for a greater good. Continuing the example, "I'm happy and grateful my house keys are in my hand." Then, do yourself a huge favor and walk away from the stressful situation in peace and with optimistic faith. Let the Universe work its magic. Before you know it, your keys will be in your hand. In the process of that occurring, you will very likely have some amazing, unexpected learning experience that you would have never had, had you not "lost your keys." As life continues to unfold, you'll soon realize why the lessons learned from the "detour event" were crucial and necessary for the ongoing manifestation of larger intentions you may have declared for your life.
The effectiveness of a positive mental energy shift is a logical, universal truth. It works every time. And for much more important and challenging situations than lost house keys...
