The Universe is like an infinite set of rooms and each room is of a specific vibrational frequency. To get into one of the rooms, you must have a key that matches the vibrational frequency of the room and your thoughts are the keys to every room in the Universe. Thus, your thoughts, feelings, and experiences must be a vibrational match to your desires in order for you to create them.
All of these rooms already exist, your dreams have already been fulfilled, and you had the experience of fulfilling your dreams the moment you created them in your mind. As you focus on a specific topic such as your desires, you are at that moment focusing on one of the rooms and its key and you are vibrationally aligning yourself to match the room of your desires. This process of vibrationally aligning with your desires then causes your thoughts, feelings, and experiences to match your desires.
