Isn't mastering an art and performance for an audience enough? The idea behind the word "mastery" is philosophical.
Never mind, there has developed a tendency if you like in the forums of late that the topic need not be philosophical in nature. Yes a dialogue on the concept of mastery is philosophical, is that what this is? Not to worry I know it is well meaning but unless it is about the philosophy around mastery it falls into the same catagory as," What's your favorite movie." not terriably philosophical though in keeping to the present trend.
