"But why? Why would you do that?" the Little Soul asked.
"You, who are a Being of such utter perfection!
You, who vibrate with such a speed that it creates a Light so bright that I can hardly gaze upon you!
What could cause you to want to slow down your vibration to such a speed that your bright Light would become dark and dense?
What could cause you -- who are so light that you dance upon the stars and move through the Kingdom with the speed of your thought -- to come into my life and make yourself so heavy that you could do this bad thing?"
"Simple," the Friendly Soul said. "I would do it because I love you."
