We humans are a process. There's nothing static. And we have this thing we call time that we look at sequentially. That’s how we accept in life that one thing happens and then the next thing happens. In this tradition, we talk about causes and conditions, which have to do with how something precedes something else in order for it to be. The oak tree is conditioned by the acorn; seeing is conditioned by there being light. All the phenomena we call life are part of conditioned reality. And the main condition of conditioned reality is that it changes. As the Dharma says: “All conditioned things are impermanent.” And we humans are a part of that.
