In the 1970's there was a TV Series about the experience of a Chinese-US boy who joined a Shoalin Temple in China to become a monk. He was taught many things such as Buddhist philosophy, and the Martial Art of "Kung Fu". To leave the Temple you had to pass a test, and snatch a pebble from the Master, something the new entrant was asked to do as a young boy (he failed that time). I suppose musically CPE Bach's "Solfeggietto" was my pebble snatching moment. I had practiced it a lot, then suddenly, I could play it, then play it again, then again.....musically I had left the temple.
