Have you realised the beauty of the effect of the wind blowing over the water and its consequences?
It causes the water to adopt a slightly wavy texture for a short period of time. The water adopts it but does not really change. It simply modifies its appearance for limited amount of time. And then quickly goes back to its original state. Seamlessly, quickly, uniformly, painlessly.
That is not very different to the way the voice works, the sound of music or even the matter at its innermost level. They are waves traveling through the space and time. Now you hear the music, a moment later is not there anymore…
Be shapeless, formless, like the water or the wind. Flow, change but never forget your original shape. Who you are.
