Affirmations are used to reprogram the subconscious mind in a desired direction. This helps to empower you to move through emotional blockages which may be limiting your opportunities to experience life to the fullest.
Every time you make a mental affirmation, your subconscious mind hears it and adjusts towards the reality of that statement. The subconscious mind does not filter, it just acts on your statements. It is important, therefore, that you feed yourself positive thoughts about who you are.
A great way to start is to make a habit of using the classic affirmation, "Every day, in every way, I am becoming better and better."
Ignore any skepticism that arises inside you when you start doing this. That's just the automatic response which comes from resistance to change. Remember, for every action in life, there is an opposite and equal reaction. When you launch into an action which will cause change, resistance to change can manifest as the automatic, opposite reaction. Just carry out your action regardless. Keep going with your affirmation, and turn it into a habit.
The phrase used in the Infinite Being Meditation is extremely powerful. "I am Infinite Being" is an affirmation of your oneness with the consciousness from which all life sprang. If you find issues arising from this, such as feeling unworthy to be aligned with All That Is, then just let those thoughts go and bring your focus back onto the phrase. You do not have to justify the words or settle any internal argument about them just because of some prior conditioning as to how someone said that you "should" think in this life.
Maintain the inner discipline to stay with the affirmation and let the issues fade away unchallenged. Your inner self knows the meaning of the words and resonates in joy with their exact and literal truth. Every time you repeat this affirmation, you strengthen your realization of your connection with Infinite Being. Any lesser thoughts then become healed in the light of the greater truth.
