Even though our toughts attract, the old saying 'be careful what you ask for, you may get it' comes to mind.
"what if two people focus their thoughts on the opposite outcome of a particular situation"
Would it not be easier to meditate on improving one-self rather than trying to change the world around them?
"What if I focus my positive thoughts and energy into being able to fly like a bird does?"
Focusing on flying in such a manner may 'win' you an airplane ride, not sprouting wings and feathers. There is a
'Serenity Prayer' in the AA Twelve Step program that I believe applies here:
"Grant to us the serenity of mind to accept that which cannot be changed; the courage to change that which can be changed, and the wisdom to know the one from the other".
Also look into the Eight Fold Path of Buddhism we can see how
Right Understanding can affect what meditation and attraction can and cannot achieve.
Well, there's my two cents on this attraction 'secret'. Good luck OnionPatch.
