A wave is made of water, but sometimes she forgets.

A wave is supposed to have a beginning, an end.

A coming up, a going down. A wave can be higher or lower than other waves,
more beautiful or less beautiful than other waves. And if the wave is caught by these notions—beginning, ending, coming up, going down, more or less beautiful—she will suffer a lot.

But if the wave realizes she is water, she enjoys going up, and she enjoys going down. She enjoys being this wave, and she enjoys being the other wave. No discrimination, no fear at all.
And she doesn’t have to go and look for water; she is water in the present moment.
