It’s possible to do a self-portrait with a slightly self-deprecating style. This was done around 2008 and at the time, I must have been reading a lot of Eastern philsophy, which is dominated by the wisdom of gurus. As my method of painting is to access the Unconscious and to let come what may, it’s possible for unexpected work to appear. As a post facto interpretation. having no arms suggests an absence. It contrasts with the associations of the guru as having wisdom and knowledge. Not knowing ironically can be a source of strength. Look up the book “The Cloud of Unknowing”.
Nothing on this site explains a painting. The point is that paintings are bigger than mere explanations. They do reflect what is in the mind of the artist, though. For example, this painting quietly critiques the concept of authority without falling into cynicism.
