What is the origin of our universe? Was it created by a god? Was there a big bang? How did it come to be?
The Buddha taught that worlds arise and collapse due to action, or karma. They arise dependently, not independently. They arise and fall continuously, without beginning and without end.
Within each of those worlds, infinite worlds unfold. There is no limit to space, no center and no border. Within the macro there is micro, and within the micro you will find macro. These infinite worlds interact in endless ways such that where one starts and the other ends is indeterminate.
And yet we feel trapped. We feel trapped in our situation. Our world feels stuck and static, like a prison. What binds us is our habitual tendencies, negative emotions and thought patterns. We are bound by erroneous views and biased perception.
There are those on the path whose sole motivation is to break free from this cycle. They want out, they want it to be done.
Then there are others who see that we can create something else.
Our actions create the world and influence innumerable worlds. Our path becomes one in which benefiting others and unlocking their own insight fulfills our path of awakening. Our particular situation is not seen as a prison, but as an opportunity for awakening. It is our naturally formed world in which we can enact benefit, in which we have potential to impact others.
And yet, neither here nor there, nor anywhere, have any of these worlds ever truly existed for a moment.
