Insight …

Artistic growth is, more than it is anything else, a refining of the sense of truthfulness. The stupid believe that to be truthful is easy; only the artist, the great artist, knows how difficult it is. That afternoon nothing new came to Thea Kronborg, no enlightenment, no inspiration. She merely came into full possession of things she had been refining and perfecting for so long. Her inhibitions chanced to be fewer than usual, and, within herself, she entered into the inheritance that she herself had laid up, into the fullness of the faith she had kept before she knew its name or its meaning.
