This drawing emerged by itself starting from the small recess in the bottom of the tree and just adding whatever came into my mind or reacting to the marks on the paper. I could probably draw a lot of interesting analogy from the image myself and my own life. It would be interesting to find out other people's thoughts of what is going on in the drawing.
This second image emerged from the marks in the tree above. I used the same repetitive mark throughout just adding shading to see how it developed. Below is a close up detail of the trunk.
