Taken from another quote by Bruce Lee about his sickness and miraculous recovery from it. "The medicine for my suffering I had within me from the beginning, but I did not take it. My ailment came from within myself but I did not observe it. Until this moment. Now I see that I will never find the light, unless, like the candle, I become my own fuel".
