It is an everlasting struggle for a lot of artists to talk about their artwork. There are a lot of reasons.
When an artist tells too much about the meaning of an artwork there is no room for interpretation. A pure experience of visual language is taken away.
An artwork that resonates with the spectator has a moment of recognition or surprise. A bond of some sorts between the spectator and the artwork. This is a very beautiful and powerful experience. Maybe even the whole reason to show art.
That bond doesn’t have to be about the message the artists wants to give. It could very well be that the message of the artist isn’t much more than his/her own interpretation.
