“Change alone is eternal, perpetual, immortal.”
Trying to define change is like building a sand castle. Just when you have the thing built it melts, dissolving into the sands of the beach once again. Life is change; all of it. The seasons change, birth and death are change, we transform from one being into another during the course of our lives, do we not? The way we think, the way we see ourselves and the world is constantly changing.
Then there is the question “am I the one who is making the change, or am I the one who is being changed?” Does it matter? Life happens anyway and if we resist change we only make it hard on ourselves.
