evidence: Of course, what you didn’t realize is that the mental strength and the "powerful beyond measure" thing were all because of the lessons I learned from you. If it hadn’t been for those lessons, there would have never been a Channel swim or any number of other things that have been great blessings in my life. There is no possible way to adequately thank you for those, but I am grateful for them every day. At the time, I was curious about your choice of the "powerful beyond measure" words, and they really stuck with me. Then, I found a quote that perfectly captured them. I don’t know if that is where you first heard them, but they really fit. Check out something that Nelson Mandela said: It is our light, not our darkness, that most frightens us."
