There is a story I like of an old Zen master who one day was asked to speak wisdom to his acolytes as they were sitting outside. He obliged. He rose and walked to the front of the students. He waited a moment to think carefully about his words, opened his mouth, and then just as he was about to speak, a bird in a nearby tree sang its beautiful warbling song. The master did not interrupt but instead simply listened and waited until the song finished, and the bird had flown away. When it had, he finally spoke: “The sermon has been delivered,” he acknowledged, and took his seat once more.
