I am attempting to give a title to something I am writing but having a bit of difficulty finding a fitting verb to proceed the word 'art.' I am centering what I'm writing around this quote: "God's greatest work on earth is man; man's master art is leading men to God." I want my title to be "_____ the Master Art." As you can probably tell, my text deals with those who engage in the master art of leading men. I've thought of several possibilities—engaging, crafting, working, building, perfecting, etc.—but none seems to fit. I would be quite grateful for any suggestions.
In other words, like a painter paints, what verb could be used for "(Master) Art"-ing?
