trick

In the Hushi Pass of Suzhou(滸市關), there was a man named Chen Yiyuan(陳一元) who left home to pursue the Dao. He constructed a house solely for cultivating his practices. He would sit alone in the house, locking himself inside. At first, he stopped eating porridge, then abstained from fruits and vegetables, drinking only water from the Stone Lake. He instructed his son to bring a jug of water each month. On the second month, when his son came to visit, the jug remained outside the door, but the water had dried up.
