You are here in your physical bodies as extensions of Source Energy, experiencing specific contrast and coming to specific new decisions about the goodness of life, and every time your experience poses a question to you, an equivalent answer is born in the experience of Source. Every time your experience poses a problem to you, an equivalent solution is born in the experience of Source. And so, because of your willingness to live and explore and experience contrast, you are giving birth to constant new rockets of desire, and All-That Is expands because of what you are living.
When it becomes your dominant intention to find good feeling thoughts, then you become one who is most often a Vibrational Match to the Source within you, and the good feeling that will then be usually present within you is your indication that you are fulfilling your reason for being and that you are continuing to keep up with the expansion of your own being.
Every experience causes you to expand, and your positive emotion in your indication that you are keeping up with that new expansion. Negative emotion is your indication that the greater part of your has moved to an expanded place but you are holding back. And so, by paying attention to the way you feel, and by continually reaching for the best feeling thoughts you can find, you will establish a rhythm of alignment that will help you immediately realise when you are straying from the goodness that you have become.
