"Lao Tzu became enlightened just by seeing a leaf, a dry leaf falling from a tree. As the leaf started falling towards the earth, he became enlightened.
Now what happened? Seeing the dead leaf falling on the wings of the wind, with no idea of its own, utterly relaxed, utterly surrendered to the winds, he had a glimpse. He must have been in a very vulnerable state. And from that very moment he became a dead leaf in the winds.
He surrendered his ego, he surrendered his clinging, he surrendered his own ideas of what should be and should not be. He surrendered all his mind, he simply became a let-go. And that's how he became enlightened."
