The song sung by everything.

Sitting very still one day, I heard a tree sing a song. That's right! It sang a long song, because it has the time.
It sang a song of the growing things, the green things, the great and small things and the glory of the light that brings us life. Then it said. "We've got roots running so very deep... that they meet!"

The birds like I, entranced and entrained just sang in harmony. Everything issues from stillness in a rhythm, a beat. That's right! The song sung by everything, can be heard by anyone that listens, cause if your truly listening, by default you are still. Stillness creates silence and in the silence one can hear.. the song sung.
