There was once a wise Zen master. People would seek his counsel and ask for his wisdom. Many would come and ask him to teach and enlighten them in the way of Zen. One day a wealthy businessman came to visit the master. 

“I have come today to ask you to teach me about Zen. Open my mind to enlightenment,” he commanded. 

The Zen master smiled and said that they should start by having a cup of tea. The master began pouring tea into his visitor’s cup. As he poured, the tea rose above the rim and spilled over the table and finally onto the robe of the wealthy man. 

The man shouted “Enough! You are spilling the tea. Can’t you see the cup is full?”

The master stopped pouring. He looked at the man and pointed to the cup. 

“You are like this tea cup, so full that nothing more can be added. Come back to me with an empty mind.”

To discover new opportunities and functions contained in existing assets, the first thing you have to do is “empty your cup” of preconceived notions and fixed identities. Then, new identities and new use will appear.
