In this world, as in a river, a piece of wood that is being carried away by the current, is seen to come into contact (for some time) with another piece which is being likewise carried away. There on the current, other pieces of wood that had been collected together, are scen to again separate from one another. Grass, sticks, and cow dung cakes are seen to be joined together. This union is merely accidental and not brought about by any set design.
