"Blue caterpillar" is a work based upon a book about Alice's adventures in Wonderland. That's the form you see. But the meaning hiding in the picture has philosiphical and religios matter. The girl is dressed in a black long dress of a nun. The caterpillar is sitting on a mushroom but at the same time this mushroom is it's body thus it gives the girl a piece of the mushroom and a glass of water which at the same time are it's body and blood. The smoking mechanism it uses and the world "blue" in the name of the picture are hints on theme of illusions, something which is not real (as any kind of religion is in reality for many people who do not study the subject deeply and seriously do not reflect but take its' shallow way.
There are two variations of this picture.
