What does this mean?

Follow your heart's path, stand fast to your morals, follow goodness(self-explanatory), and enjoy every aspect of your life.

The Way is, of course, something you should understand from the Master's other teachings. Once your heart is following this well-defined, good path, then the other things fall into place. When one relies on good morals and the power of good morality, one can easily follow goodness. Enjoying the arts is simply one way to experience the Way, the moral power, and the goodness that are all a part of the best life.
