Just came upon this Zen koan and love it so much:
Seijo’s Two Souls
Chokan had a very beautiful daughter named Seijo. He also had a handsome young cousin named Ochu. Joking, he would often comment that they would make a fine married couple. Actually, he planned to give his daughter in marriage to another man. But young Seijo and Ochu took him seriously; they fell in love and thought themselves engaged. One day Chokan announced Seijo’s betrothal to the other man. In rage and despair, Ochu left by boat. After several days journey, much to his astonishment and joy he discovered that Seijo was on the boat with him!
They went to a nearby city where they lived for several years and had two children. But Seijo could not forget her father; so Ochu decided to go back with her and ask the father’s forgiveness and blessing. When they arrived, he left Seijo on the boat and went to the father’s house. He humbly apologized to the father for taking his daughter away and asked forgiveness for them both.
“What is the meaning of all this madness?” the father exclaimed. Then he related that after Ochu had left, many years ago, his daughter Seijo had fallen ill and had lain comatose in bed since. Ochu assured him that he was mistaken, and, in proof, he brought Seijo from the boat. When she entered, the Seijo lying ill in bed rose to meet her, and the two became one.
Zen Master Goso, referrring to the legend, observed, “Seijo had two souls, one always sick at home and the other in the city, a married woman with two children. Which was the true soul?”
