In a quiet village, two monks stood on the bank of a wide river. The older monk asked the younger, “How do you cross this river?”
The younger monk pointed at the grand bridge a short distance away, “Through that bridge, master.”
The older monk shook his head, "You see a bridge, yet the river flows beneath. In seeking to cross, you are already on the other side. Tell me, where is the true bridge?
At that moment, the young monk became enlightened, supposedly, because that’s how most zen koans end.
