Bokma considers life a collection of processes where one material transforms into an other. It's his vision that, in order to see the essence of life, you have to view her from her material appearance.

Voltooid leven expresses the idea that life is originated in rough materials, that it moves forward in a cyclic way and when it dies it disintegrates into rough materials again The sculpture Voltooid leven is made out of plywood, glass fibre, epoxy resin, black fillers.
