Because we're not just physical things defined by the world, but the world is made of our actions, we can use the processes of actions to get out of this web of actions that we’ve woven for ourselves.

"Remember the Buddha’s analysis of what a world is: your six senses. And remember that samsara is not a place. It’s an activity. It’s made out of your actions. That’s where the danger lies — in your actions — but it’s also where the promise lies.

If we were just physical things defined by the world, there’d be no way we could use the processes of the physical world to get out of the physical world. But because the world is made of our actions, we can use the processes of actions to get out of this web of actions that we’ve woven for ourselves.

This is where the fact of the complexity of kamma actually works to our advantage. It does have a disadvantage in that often we’re very confused as to what’s going to be helpful. Something looks good and looks okay and we do it and then we find out quite a while later that it wasn’t good at all in the long term. But the complexity of kamma also gives us freedom of choice. And we have the Buddha and we have the Dhamma to give us some basic instructions as to what’s skillful and what’s not, at the same time teaching us how to develop the qualities of mind where we can start to see these things for ourselves.

That’s when you begin to realize that you can use your actions to take apart this web of actions."
