Yes it does. Because for sure the tree is hearing it, whoever else may or may not be around.
Don't you believe that a tree can be that sensitive? Why, it is the most sensitive of life forms. Don't let that bark fool you. That's not keeping out the sensation. It's a skin of the most sensitive sort. And when the tree falls, that skin feels its death at the moment of passing. And experiences the sound waves from the ensuing crash. And feels joy and gratitude all the time.
What teachers are these trees we find around us? Cherish them, cherish them.
