The mind is a creative instrument. It can be expansive and it can also be limiting.
Often times the mind plays tricks on you when you get your first taste of accomplishment. These tricks will appear as thoughts, such as; It can't be possible, it was just a coincidence. Let me assure you that there is no such thing as coincidence.
When such thoughts occur, give thanks and acknowledge your infinite power for the accomplishment. By doing this, you gain awareness and more and more consciousness with regard to what you think you create. You become aware that there is a law, which actually works at all times.
The infinite power and what it creates is beyond the mind. Please do yourself a great service and don't try to understand it. Just be in gratitude of the accomplishment with abundance, happiness and success.
