There have been many instances where I did not appreciate some work of art the first time I approached it. Often I have discovered new meanings in familiar objects. I did not appreciate John Coltrane's "Naima" until one day it enveloped me in epiphanies of new understanding. The same was true for Albert Camus' "The Rebel" and "Spirit" by Willie Nelson, the works of Miro and a host of other works of art.
A tree appears differently in morning than it does at night, or in winter than summer or in rain than drought. The point is to keep looking at the tree to gain new and different appreciations.
