Receiving involves feeling the way you will feel once your desire has manifested. Felling good now puts you on the frequency of what you want. Starting with something small, like a parking space is an easy way to experience to law of attraction in action.
The only reason why people do not have what they want is because they are thinking more about what they don't want than what they do want. Listen to your thoughts, and listen to the words you are saying. The law is absolute and there are no mistakes. - Rhonda Byrne
