You are greatly encouraged to allow these works to impress their own meanings on you before reading the titles and meanings prescribed to them here. Once you have read the given names and explanations, the purity of your own impressions of the pieces will be forever tainted.
While the artist has meaning and intentions in mind for each work, his impressions of the work are no better than yours. He does not paint to send a message per se, he paints to send an invitation to contemplate and feel on your own terms.
That said, if your impressions happen to align with the artists intent, rest assured that makes him especially pleased.
