The first rule about affirmations is that you "can never fool yourself".
Write down your affirmation, now repeat it aloud. Does your mind recoil in horror? Does your heart sink? Do you feel a weakening sensation? Or worse still, do you hear uncontrollable laughter or derision in your mind?
That is your clear sign that the affirmation you wrote is not only inappropriate but it is also greatly damaging. This is because the affirmation is energizing the opposite belief that you have about the subject.
This is the reason why, wherever the insane teachings of the Merchants of the Law of Attraction have proliferated, great economic powers have been reduced to bankruptcy. People are literally being taught to energize the opposite of what they want in their lives.
The fact is that if a person with a poverty mindset affirms wealth, that person will get more poverty--there is no escaping this truth because it is how creation works.
Let us say that you are affected by a scarcity mentality, a poverty mind set program.
The symptoms of that will be: scarcity, constant anxiety about money, inability to get out of debt, unfortunate recurring events that cause you to lose money.
If this is you, then realize that this scarcity mindset is a program that you inherited from your significant people around you. It is not a "fault" of your own and it has nothing to do with "intelligence" or "abilities".
So how do we "affirm" wealth if our mind is unwilling to accept it?
The answer is incredibly simple (all useful concepts are simple).
Formalize your affirmation in such a way that it will not challenge your beliefs.
Your mind is absolutely certain that you will never be wealthy :-)
So affirming "There is infinite wealth all around me" is unlikely to cause too much grief to your poverty mindset. In fact it is likely to escape scrutiny. After all, it is an undeniable truth--there is infinite abundance all around you.
Stay with that feeling of wealth. Do not try to visualize yourself as being wealthy, as doing so will send alarm signals to your mind and it will sabotage the process.
Affirming on location.
This will gently cause your mind to start to 'believe" that there is enough wealth for everyone and that you too have the right to be wealthy, abundant and happy.
