After a while, the wave has forgotten that it has risen from the ocean. It gets busy in carving this false identity for itself. And before it realizes, it falls back into the ocean. Whether the wave likes it or not, whether it wants to believe it or not, it must fall back into the ocean because that is where it came from. It has no choice. It came from the ocean and it must go back into the ocean.
All problems arise when the wave thinks it is different from the ocean and resists it. Different waves start to compare themselves with each other about which one is better and even fight wars with each other. If the wave understands that once it falls back it will emerge elsewhere as another wave, then there is no need to resist the fall. It will relax and enjoy. The wave will suddenly start to enjoy its play in the ocean.
If the wave understands that other waves present in that vast mighty ocean are the same water, the wave will suddenly feel a deep connection with other waves because it knows that at the core, they are all one. If we understand this simple theory of life — that we came from the same Source and we return to it — we realize that we are connected to something much greater than our individual self.
