The Universe does not know if the vibration you are offering is because of what you are imagining, or because of what you are observing. In either case, it is responding.
Emotion is your guidance or your response to your vibration. Your emotion does not create. Emotion is your indicator of what you are already creating. As you think, you vibrate. And it is your vibrational offering that equals your point of attraction. So, what you are thinking and what is coming back to you is always a vibrational match. The emotion (your Guidance System) is telling you what’s coming.
