Action, motion, change and transformation are all aspects of Manipura Chakra.
Seen in some cultures as a destructive force, Shiva the destroyer to the Hindus for instance, this elemental force is that which changes things from what they were into what they are becomming - so these things must cease to be what they were; it may seem like the end but it is always just a new beginning. As the symbol blows apart and fades away, it is only to begin anew again.
