All things are interrelated. Everything in the universe is a part of a single whole. Everything is connected in some way to everything else. It is therefore possible to understand something only if we can understand how it is connected to everything else. All of creation is in a state of constant change.
Nothing stays the same except the presence of cycle upon cycle of change.
One season falls upon the other. Human beings are born, live their lives, die and enter the spirit world. All things change. There are two kinds of change. Both of these kinds of change are necessary and are always connected to each other.
