“Understanding” abstraction

Someone (who works in design) asks me how to “understand” abstract paintings. Obviously there has to be an entry point for non-representational, non-figurative art. Although I think the word “understand” gives too much emphasis to Left Brain / analytical and reductive approaches to what is an art work, it is helpful for some of us to have a way of thinking about abstraction. So I did a drawing summarising my process of painting. Even the basic idea that I am seeking to echo the natural can quickly provide a point of entry.
